All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this application and the drawings described above, are intended to cover non-exclusive inclusions. For example, a process, method, or system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," and "third," etc. are used to distinguish between different objects and are not used to describe a particular order.
An embodiment of the present application provides a wireless communication method, which is applied to any wireless communication device with a wireless communication function, such as a mobile phone, a tablet computer, an intelligent bracelet, a personal digital assistant, a notebook computer, a wireless router, a point of sale (pos) device, a wireless landline phone, and a facsimile machine.
As shown in fig. 1, a wireless communication method provided in an embodiment of the present application includes:
step S101, acquiring the target power of the wireless communication signal required to be output.
In this embodiment, the target function of the wireless communication signal to be output is the power of the wireless communication signal to be finally output to the external device.
In a specific application, the initial power of the wireless communication signal generated by the signal transmission link inside the wireless communication device is different from the power of the wireless communication signal finally output to the external device, because the wireless communication signal is lost in the process from generation to final transmission, and the initial power is larger than the target power.
Step S102, obtaining initial power corresponding to target power according to the pre-stored incidence relation between the target power and the initial power and the target power.
In a specific application, the association relationship between the target power and the initial power may exist in the form of a mapping relationship table, a correspondence table, a look-up table (LUT), or the like, and may also be implemented by using other data tables or Random Access Memory (RAM) type storage media having input data with the same function as the display lookup table, that is, input data corresponding to the input data, or output data corresponding to the input data.
As shown in fig. 2, in one embodiment, step S102 is preceded by:
step S201, controlling a signal transmitting link to generate wireless communication signals with different initial powers, and acquiring a target power corresponding to each initial power;
step S202, establishing and storing the incidence relation between each target power and the corresponding initial power.
In a specific application, in a test stage before factory shipment, a signal transmission link needs to be controlled in advance to generate and transmit wireless communication signals with different initial powers, then a power detection circuit detects and obtains power (namely target power) of a wireless communication signal which is actually output to an external device and corresponds to each initial power, records target power corresponding to each initial power, and when steps S201 and S202 of the wireless communication method are executed, obtains target power corresponding to each initial power which is recorded in advance, and establishes and stores an association relationship between each target power and the corresponding initial power.
As shown in fig. 3, in one embodiment, a schematic diagram of a closed-loop control link formed by a signal transmission link and a power detection circuit is exemplarily shown; the signal transmitting link comprises a wireless communication module 1, a power amplifier 2, a filter 3 and an antenna 4 which are sequentially in communication connection, the power detection circuit comprises a power detection device 5 and a rectifying device 8, the power detection device 5 is in communication connection among the filter 3, the antenna 4 and the rectifying device 8, and the rectifying device 8 is in communication connection between the power detection device 5 and the power amplifier 2.
In a specific application, the power detection device may specifically be a power detection chip, and the rectifier device may specifically be a rectifier diode. When the rectifier device is a rectifier diode, the anode of the rectifier diode is in communication connection with the power detection device, and the cathode of the rectifier diode is in communication connection with the power amplifier, so that a signal output by the power detection device is transmitted to the power amplifier in a single direction through the rectifier diode, and finally is fed back to the wireless communication module through the power amplifier, so that a wireless communication signal generated by the wireless communication module is prevented from being transmitted to the power detection device through the power amplifier and the rectifier diode, and the detection result is prevented from being interfered.
In a specific application, the wireless communication module may include at least one of a WiFi module, a bluetooth module, a 2.4G module, a GSM module, a GPRS module, and a ZigBee module according to a difference of a communication mode of the wireless communication device.
In a specific application, the target power corresponding to each initial power can be tested in advance by using the closed-loop control link formed by the signal transmission link and the additionally arranged power detection circuit shown in fig. 3 in a test stage before factory shipment.
In one embodiment, step S202 includes:
step S301, calculating the difference between each target power and the corresponding initial power;
step S302, establishing and storing an association relation between each target power and the corresponding difference value.
In a specific application, the association relationship between the target power and the corresponding difference may exist in the form of a mapping relationship table, a correspondence table, a look-up table (LUT), or the like, and may also be implemented by using other data tables or Random Access Memory (RAM) storage media having input data with the same function as the LUT, that is, input data and output data corresponding to the input data.
As shown in fig. 4, an exemplary table of correspondence between a plurality of different target powers (denoted as target power 1, target power 2, … …, target power N in fig. 4) and their corresponding differences (denoted as difference 1, difference 2, … …, difference N in fig. 4); wherein N is an integer of not less than 1.
In one embodiment, based on steps S301 and S302, step S102 includes:
step S401, searching a difference value corresponding to a target power according to a pre-stored incidence relation between the target power and a difference value corresponding to the target power and the target power;
and S402, calculating to obtain initial power corresponding to the target power according to the target power and the difference value corresponding to the target power.
In specific application, by calculating the difference between each target power and the corresponding initial power, establishing and storing the association relationship between each target power and the corresponding difference, the corresponding difference can be found according to the target power when the wireless communication signal with any target power needs to be output, and the initial power corresponding to the target power can be calculated according to the target power and the corresponding difference.
In a specific application, the difference between the target power and the initial power corresponding to the target power = target power-initial power, and then the calculation formula for calculating the initial power corresponding to the target power according to the target power and the difference corresponding to the target power is as follows: target power-difference = target power- (target power-initial power) = initial power.
Step S103, controlling a signal transmitting link to generate a wireless communication signal with initial power corresponding to the target power so as to output the wireless communication signal with the target power.
In a specific application, since the wireless communication signal with the initial power generated by the signal transmission link has a link loss, the power of the wireless communication signal which is finally output is a target power which is smaller than the initial power.
As shown in fig. 5, a schematic diagram of a signal transmission link is exemplarily shown; the signal transmitting link comprises a wireless communication module 1, a power amplifier 2, a filter 3 and an antenna 4 which are sequentially in communication connection.
In the above embodiments, the connection lines with arrows in fig. 3 and 5 represent communication connections, and the arrow direction represents a signal transmission direction.
In a specific application, when the power accuracy of the signal transmitted by the communication device is controlled through the closed-loop control link shown in fig. 3, the additionally arranged power detection circuit increases the cost of the communication device, and the wireless communication signal with the target power is output through the signal transmission link shown in fig. 5 without additionally arranging the power detection circuit, so that the cost of the communication device can be effectively reduced.
In the wireless communication method provided by the above embodiment, the target power of the wireless communication signal to be output is obtained, the initial power corresponding to the target power is obtained according to the pre-stored association relationship between the target power and the initial power and the target power, and the signal transmission link is controlled to generate the wireless communication signal of the initial power corresponding to the target power so as to output the wireless communication signal of the target power.
