The present invention relates to a mobile communication terminal, and more particularly, to optimize power control capability of a termination amplifier module through an abnormality check procedure of a digital signal, a correction procedure of a power check signal, and the like, thereby causing an abnormality of an amplitude component. The present invention relates to a mobile communication terminal capable of effectively improving the user's convenience in using a terminal by effectively suppressing an increase in unnecessary power consumption due to a phenomenon.

Recently, with the rapid development of electric, electronic and communication related technologies, mobile communication terminals are also showing a rapid spreading speed.

Unlike a conventional wired communication terminal, such a mobile terminal provides a mobile communication infrastructure between users based on a series of wireless communication networks, and therefore, in a conventional mobile communication terminal system, a user can communicate with a desired counterpart regardless of location. The advantage of making a call freely can be easily obtained.

Such a conventional mobile communication terminal, for example, a mobile communication terminal 1 having a signal modulation processing system of 8-Phase-Shift Keying (hereinafter referred to as "8-PSK"). Under the system, as shown in Fig. 1, an audio signal (e.g., a voice signal) received through the antenna 12 is typically used for the call processing related module 8 and the base-band module 4. And a mechanism for outputting to the speaker 10 via the audio input / output processing module 7, and the audio signal input through the microphone 9 is the audio input / output processing module 7 and the base-band. After passing through the module 4, the modulation module 5, the modulation signal transmission processing module 6, etc., it is amplified by the terminal amplification module 11, and then takes a mechanism that is externally output through the antenna 12. Done.

In this case, the terminal control module 2 forms a series of intimate connection relationships with the call processing related modules 8, and also has a close signal connection with the base-band module 4 via the logic interface module 3. By forming the relationship, a series of audio signal transmission / reception procedures by the action of each module is performed to control the overall operation so that the normal operation can be performed without any problems.

At this time, as shown in the figure, a part of the digital signal output through the antenna 12 is fed back to the modulation signal transmission processing module 6 side through the coupler 13 disposed adjacent to the antenna 12. After back), the mechanism is re-input to the termination amplifier module 11, in this situation, the termination amplifier module 11 is a power check reference signal transmitting unit 4a disposed in the base-band module (4) After inputting a predetermined power check reference signal from the power supply reference signal, feedback is inputted from the value α of the power check reference signal I1 and the modulation signal transmission processing module 6 as shown in FIG. 2. The procedure of comparing the value β of the signal I2 is carried out, and if the value β of the feedback signal I2 is different from the value α of the power check reference signal I1, the amplification of the signal I2 is performed. By increasing or decreasing the power, the value β of the corresponding feedback signal I2 becomes the value α of the power check reference signal I1. By adjusting to be equal to (i.e., adjusting from β value to α value), the transmission power of the digital signal finally output through the antenna 12 is induced to maintain a constant value overall.

However, under such a conventional system, since the digital signal finally output through the antenna 12 is simply fed back to the modulated signal transmission processing module 6 without a separate check procedure, various malicious factors existed around the terminal. For example, a part of the envelope AE1 of the amplitude component AE constituting the feedback signal I2 is over-shooted by the influence of temperature, radio waves, or physical changes in hardware components. Even if it is causing, the terminal side can not grasp this at all.

Further, in this situation, even if the over-shoot problem of the amplitude component AE is difficult to grasp, the power check reference signal I1 which is an absolute reference to the output power control procedure of the terminal amplification module 11 is the amplitude component AE. Since the terminal amplification module 11 always has a fixed value regardless of the over-shoot phenomenon, the amplification power of the terminal amplification module 11 only maintains a constant output power of the digital signal output through the antenna 12. It is not possible to flexibly adjust its amplification power so that the overshoot of the amplitude component (AE) can be solved.

Of course, due to this problem, if the amplitude component (AE) over-shoot phenomenon of the digital signal finally output through the antenna 12 is left unattended without any action, the overall power consumption of the terminal will be unnecessarily significantly increased. In the aftermath, the user is forced to take great inconvenience in using the mobile communication terminal.

Accordingly, an object of the present invention is to secure and compare a predetermined spec amplitude value to a part of a terminal and an amplitude component of a digital signal finally output through an antenna to check an abnormal phenomenon, such as an over-shoot phenomenon of the digital signal. Computer module> and <computer module that can correct the output of power check signal by varying the value of the power check signal to the terminal amplification module according to the abnormality of the digital signal> and systematically interlock and arrange the terminal amplification. By inducing the module to naturally adjust its amplification power to the overshoot of the amplitude component, the digital signal finally output through the antenna can flexibly retain the normal amplitude component regardless of changes in the external environment. There is a guide to help.

Another object of the present invention is to optimize the power control capability of the termination amplifier module through an abnormality check procedure of the digital signal, a correction procedure of the power check signal, and the like, thereby, unnecessary power of the terminal due to an abnormal phenomenon of the amplitude component. By effectively suppressing the increase in consumption, the user's convenience in using the terminal is naturally improved.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, in the present invention, a terminal control module for overall control of the transmission and reception procedures of an audio signal, a modulation module that is computer controlled by the terminal control module and modulates the audio signal, and the modulation The digital signal modulated by the module is analyzed for each component, and a modulated signal transmission processing module for transmitting and processing amplifies the digital signal processed by the modulated signal transmission processing module according to a power check reference signal value, and externally via an antenna. A power check criterion that checks whether the terminal amplifying module outputs and the digital signal finally output from the terminal amplifying module side are abnormal, and corrects the power check reference signal value to another power check reference signal value according to the abnormality. A mobile communication terminal comprising a combination of a signal value correction module is disclosed.

Hereinafter, with reference to the accompanying drawings, a mobile communication terminal according to the present invention will be described in more detail.

As shown in FIG. 3, in the mobile communication terminal 100 according to the present invention, for example, under the mobile communication terminal system having the 8-PSK signal modulation processing system, an audio signal (for example, received through the antenna 112) Voice signal) takes a mechanism that is output to the speaker 110 via the call processing related module 108, the base-band module 104, the audio input / output processing module 107, etc., the microphone 109 The audio signal input through the audio input / output processing module 107, the base-band module 104, the modulation module 105, the modulation signal transmission processing module 106, and the like, and then the termination amplification module 111. It is amplified by, and then takes a mechanism that is externally output through the antenna (112).

In this case, the base-band module 104 serves to code and decode the audio signal transmitted / received, for example, and the modulation module 105 receives the audio signal processed by the base-band module 104. For example, it modulates to fit the 8-PSK signal modulation processing system.

At this time, the terminal control module 102 forms a series of close signal connection relationships with the call processing related modules 108, and close signal connection with the base-band module 104 via the logic interface module 103. By forming the relationship, a series of audio signal transmission / reception procedures by the action of each module is performed to control the overall operation so that the normal operation can be performed without any problems.

Here, in the above call processing related module 108, for example, when an external audio signal is received through the antenna 112, a receiving amplification module for compensating and amplifying a gain for the received signal, the signal amplified through the receiving amplification module After detecting, the detection module demodulates and outputs the corresponding audio signal, the mixing module that mixes and outputs the control signal received through the antenna with the intermediate frequency signal, and the digital waveform of the high frequency control signal output through the mixing module. After comparing the decoder and the signal output through the decoder with a unique address, the discrimination module for transmitting the result of the comparison to the terminal control module 102 may be flexibly selected.

Of course, it will be obvious that the specific configuration and function of the above-described call processing related modules 108 may be variously modified according to circumstances.

At this time, as shown in Figure 4, the modulated signal transmission processing module 106 utilizes a built-in signal synthesis unit 106a, the digital signal modulated by the modulation module 105, for example, I-signal (Inphase signal, a Q-signal (Quadrature signal) is synthesized, and then converted into an intermediate frequency signal and outputs to the component analyzer 106b. In this situation, the component analyzer 106b is synthesized. After analyzing the intermediate frequency signal by the component (amplitude component and phase component), and serves to output the analyzed signal to the terminal amplification module 111.

Here, a part of the digital signal output from the terminal amplification module 111 is fed back to the feedback management unit 106c of the modulated signal transmission processing module 106 through the coupler 113 disposed adjacent to the antenna 112. In this case, the terminal amplification module has a power check reference signal I1: as shown in FIG. 5. As will be described later, the power check reference signal is managed by the power check reference signal correction module according to the present invention, and the feedback signal I2 fed back from the modulated signal transmission processing module 106. Will be compared with each other.

Under the circumstances in which such a procedure is in progress, the present invention takes measures to further arrange the power check reference signal correction module 120 forming the gist of the present invention in a part of the terminal.

In this case, the power check reference signal correction module 120 receives a part of the final digital signal output from the terminal amplification module 111 through the coupler 113 disposed adjacent to the antenna 112, and then returns the feedback. The process of checking whether the signal is abnormal and correcting the value α of the previous power check reference signal I1 to the value γ of another power check reference signal I3 is performed according to the abnormality. .

Of course, the feedback signal handled by the power check reference signal correction module 120 is coupled to the coupler 113, similar to the feedback signal I1 fed back to the modulated signal transmission processing module 106 through the coupler 113. Because they are fed back, they can be regarded as the same signal.

At this time, as shown in Figure 4, the power check reference signal correction module of the present invention is a combination of the signal value comparison unit 122, power check reference signal value correction unit 124, rectifier 121, etc. Will be taken.

In this situation, the signal value comparison unit 122 is electrically connected to the terminal termination amplifier 111 through the coupler 113, and as shown in FIG. 5, the feedback signal I2: Since the feedback signal is the same as the signal fed back to the modulation signal transmission processing module side, the amplitude component AE of the following reference numerals is used in comparison with a predetermined predetermined amplitude value S1, S2, and corresponding amplitude. The function of checking whether the component AE is abnormal, for example, whether <the part of the envelope AE1 of the amplitude component AE is causing an over-shoot phenomenon>.

In addition, the power check reference signal value corrector 124 communicates with the signal value comparator 122 while being electrically connected to the signal value comparator 122 and, if the signal value comparator 122 is amplitude When the abnormality of the component AE is confirmed, the value α of the predetermined power check reference signal I1 is newly corrected to generate a new power check reference signal value γ, and the generated power check reference signal is completed. By transmitting the value γ to the terminal amplification module, the terminal amplification module 111 adjusts and operates its amplification degree in accordance with the new power check reference signal value γ, and through this, the final digital output It serves as a guide to reliably manage signals.

At this time, the rectifier 121 converts the feedback signal output from the coupler 113 side into a DC signal while being disposed on an electrical connection path between the coupler 113 and the signal value comparator 122. <Feedback signal inputted from the modulation signal sending processing module 106 to the terminal amplification module 111> and <feedback signal operated by the signal value comparison unit 122> are the same. It will serve to help you lose.

Here, for example, the above-described base-band module 104 is further provided with a spec amplitude value providing unit 130 that is electrically connected to the signal value comparison unit 122, in this case, the spec amplitude value providing unit While the 130 stores and manages the predetermined ideal specification amplitude values S1 and S2, the signal amplitude comparison section 122 selects and provides these specification amplitude values S1 and S2 to the signal value comparison section 122 as necessary. It serves to assist the procedure to check whether the series of feedback signals (I2) abnormal by the 122 can proceed normally without any problems.

In the module environment of the present invention, since the front coupler 113 is slightly separated from the antenna 112, the feedback signal I2 fed back through the coupler 113 is terminated and amplified. Compared to the actual signal size output from the) side, it is inevitably forced to attenuate, despite this situation, the signal value comparison unit 122 has no choice but to receive the digital signal feedback through the coupler 113 Therefore, if the spec amplitude value output from the spec amplitude value providing unit 130 is input to the signal value comparator 122 without any further action, the signal value comparator 122 may determine the spec spec. Due to the fundamental difference between the S1, S2) and the feedback signal I2, it is impossible to proceed normally with a series of feedback signal checks as desired.

In the present invention, in consideration of such a problem, as illustrated in the drawing, an action of additionally disposing the attenuator 123 on the electrical connection path between the signal value comparison unit 122 and the spec amplitude value providing unit 130. Take a look.

Of course, in this case, the spec amplitude values S1 and S2 output from the spec amplitude value providing unit 130 are similar to those of the feedback signal I2 that is attenuated through the coupler 113. As a result, the signal value comparator 122 can normally perform the procedure for checking whether the feedback signal I2 is abnormal or not without any problem.

Hereinafter, a detailed function performing procedure of the power check reference signal correction module 120 having the above-described configuration will be described.

First, a part of the digital signal outputted from the terminal amplification module 111 through several pre-processing procedures is provided through a coupler 113 disposed adjacent to the antenna 112 to feed back the feedback management unit of the modulated signal transmission processing module 106 ( After being fed back to 106c), it takes a mechanism to re-enter the component analyzing unit 106b again to the terminal amplification module 111, and in this situation, the terminal amplifying module 111 is shown in FIG. Likewise, a procedure of comparing the value? Of the power check reference signal I1 with the value? Of the feedback signal I2 fed back from the modulated signal transmission processing module 106 is performed.

In this situation, the signal value comparison unit 122 of the power check reference signal correction module 120 receives the feedback signal I2 through the coupler 113, and then the amplitude component AE of the corresponding feedback signal I2. ) Is compared with a predetermined specification amplitude value (S1, S2).

At this time, for example, when it is determined that a part of the envelope AE1 of the amplitude component AE constituting the feedback signal I2 is out of the spec amplitude values S1 and S2 and is causing an over-shoot phenomenon, the signal value comparator Immediately, 122 notifies the power check reference signal value correction unit 124 of the fact.

Thus, when the abnormality of the amplitude component is notified by the signal value comparison part 122, the power inspection reference signal value correction part 124 immediately corrects the value (alpha) of the predetermined power check reference signal I1. A new correction is performed to generate a power check reference signal I3 having a new value γ, and transmit the generated power check reference signal I3 to the terminal amplification module 111. Reference numeral 111 naturally recognizes the value α of the power check reference signal I1 as its reference as the value γ of the new power check reference signal I3.

As described above, in the situation where the value α of the existing power check reference signal I1 is changed to the value γ of the new power check reference signal I3, the termination amplification module 111 performs the value of the feedback signal I2. When β is different from the value? of the power check reference signal I3, its amplification power is lowered so that the value β of the feedback signal I2 becomes the value of the new power check reference signal I3. To be equal to γ), the value of the corresponding signal is adjusted downward (ie, from β value to γ value).

Of course, when the value β of the feedback signal I2 is adjusted downward (ie, adjusted from β value to γ value) to be equal to the value γ of the new power check reference signal I3, of course, the corresponding feedback The envelope of the amplitude component AE constituting the signal I2 is also adjusted downward, so that it can be naturally included in the spec amplitude values S1 and S2, and eventually, the digital signal finally output through the antenna 112 can be Irrespective of changes in the environment, it is possible to flexibly retain normal amplitude components without defects such as over-shoots.

This invention can be variously modified depending on the situation.

For example, in the present invention, the above-described power check reference signal value correction unit 124 may be modified to be included in the base-band module 104 instead of the power check reference signal correction module 120.

As another example, in the present invention, the specification amplitude value providing unit 130 described above may be modified in a computerized manner within the power check reference signal correction module 120 instead of the base-band module 104.

As described in detail above, in the present invention, a part of the terminal secures and compares the <predetermined specification amplitude value with the amplitude component of the digital signal finally output through the antenna, so that an abnormal phenomenon such as an over-shoot Computational module for checking the phenomenon> and <computer module for correcting output by varying the value of the power check signal to the terminal amplification module according to the abnormality of the digital signal> are systematically interlocked. By inducing the termination amplifier module to naturally adjust its amplification power to the over-shoot phenomenon of the amplitude component, the digital signal finally output through the antenna is able to flex the normal amplitude component regardless of the change of the external environment. You can guide them to hold them.

In addition, the present invention optimizes the power control capability of the terminal amplification module through an abnormality check procedure of the digital signal, a correction procedure of the power check signal, and the like, thereby, unnecessary power consumption of the terminal due to an abnormal phenomenon of the amplitude component. By effectively suppressing the increase, the user's convenience in using the terminal can be naturally improved.

The present invention is not only limited to the mobile communication terminal, but has an overall useful effect in various types of electronic devices using a wireless transmission / reception mechanism.
