Description

technical field

The present application relates to the field of communication technologies, and in particular, to a method and device for amplifying a wireless signal.

Background technique

With the continuous development of communication technology, cellular-based Narrow Band Internet of Things (NB-IoT) emerges as the times require. In order to reduce deployment costs, NB-IoT network is directly deployed in the Global System for Mobile Communication (Global System for Mobile Communication) , GSM) network, and share the same frequency band with the GSM network, where the frequency band refers to the frequency of the signal within a range, the bandwidth of the GSM signal is 200KHZ, and the bandwidth of the NB-IoT signal is 3.75KHZ and 15KHZ.

Usually, in order to expand the signal coverage of the macro base station and improve the communication quality, the operator usually deploys a large number of wireless signal amplification devices in the GSM network to amplify the wireless signal. In the mid-term, wireless signal amplification equipment usually uses wireless repeaters, including broadband repeaters and frequency-selective repeaters.

In the prior art, when a wireless signal amplifying device amplifies a wireless signal including a GSM signal and an NB-IoT signal, the following methods are mainly used:

The first way is to amplify the received wireless signals of all frequency bands to the set power through the broadband repeater, that is, the amplified power of the wireless signals of all frequency bands is the set power.

However, in this way, since the GSM signal and the NB-IoT signal are amplified to the same set power, and the bandwidth gap between the GSM signal and the NB-IoT signal is relatively large, therefore, through the set power and bandwidth difference The ratio, the difference between the power spectral density of the GSM signal and the NB-IoT signal obtained respectively is large, which will increase the loss of the components of each device in the network system, reduce the system capacity of the NB-IoT signal, and the success rate of communication services. .

The second method is: using the wireless signal demodulation method through the frequency-selective repeater, among all the received wireless signals, determine the wireless signal of the set frequency band, and according to the set power to the wireless signal of the set frequency band. to zoom in.

However, in this way, since the wireless signals in the set frequency band are also amplified to the same set power, when amplifying the GSM signal and/or the NB-IoT signal, the GSM signal and the NB-IoT signal cannot be amplified separately. The IoT signal is amplified according to different amplification factors, and since both the GSM signal and the NB-IoT signal have corresponding amplification requirements, only amplifying one of the GSM signal and the NB-IoT signal cannot meet the needs of signal amplification. need.

Further, analyzing the GSM signal and the NB-IoT signal contained in the wireless signal by means of wireless signal demodulation is costly.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the protection of the present application.

In order to reduce the cost of wireless signal amplification, for different types of wireless signals, amplify different multiples and improve the success rate of communication services, in the embodiment of the present application, a method for amplifying wireless signals is designed. Perform bandwidth analysis to obtain the first signal power of the first signal whose bandwidth is the first preset bandwidth value, and the second signal power of the second signal whose bandwidth is the second preset bandwidth, and calculate the first The signal power ratio between the signal power and the second signal power, and based on the signal power ratio, power distribution is performed for the first signal and the second signal, and further, based on the maximum amplification factor and the maximum power value, the first output power and The second output power is adjusted, and the first signal power is amplified to the adjusted first output power, and the second signal power is amplified to the adjusted second output power.

The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention, and the present application The embodiments in and features in the embodiments can be combined with each other.

Referring to FIG. 1, it is a flowchart of amplifying a wireless signal. In the embodiment of the present application, it is mainly applied to a wireless signal amplifying device, and the specific process of amplifying a wireless signal is as follows:

Step 100: The terminal performs bandwidth analysis on the received wireless signal, and determines to include a first signal whose bandwidth is a first preset bandwidth value and a second signal whose bandwidth is a second preset bandwidth value.

Specifically, the terminal receives the wireless signal sent by the signal transmitting device, and analyzes the bandwidth of the wireless signal to determine the first signal and the second signal included in the wireless signal.

Optionally, the terminal may be a wireless signal amplifying device, the signal transmitting device may be a base station or an intelligent terminal, etc., and the first signal and the second signal may be a GSM signal, an NB-IoT signal, and a Long Term Evolution (Long Term Evolution, LTE) signal. any two of them.

Since the bandwidth of various signals is different, for example, the bandwidth of the GSM signal is 200KHZ, and the bandwidth of the NB-IoT signal is 3.75KHZ and 15KHZ, therefore, the wireless signal can be analyzed by the bandwidth to determine various types of signals .

Optionally, the first signal is set as a GSM signal, the first preset bandwidth value is 200KHZ, and the second signal is set as an NB-IoT signal, and the second preset bandwidth value is 50KHZ.

Wherein, setting the second preset bandwidth value to 50KHZ can reduce the detection accuracy when the terminal performs bandwidth analysis, and reduce the detection cost.

In this way, various signals can be distinguished by the bandwidth, which avoids the problem of high cost when distinguishing various signals by demodulating wireless signals in the prior art, and reduces the cost of analyzing wireless signals.

Step 101: The terminal obtains the first signal power of the first signal and the second signal power of the second signal, and calculates the ratio of the first signal power and the second signal power to obtain the signal power ratio.

Step 102: The terminal performs power allocation on the preset total power based on the acquired signal power ratio, and determines the first output power allocated to the first signal and the second output power allocated to the second signal.

Specifically, when step 102 is executed, the following methods may be used:

The first way is: when the terminal determines that the signal power ratio is not lower than the first preset ratio, the terminal performs power distribution on the total power according to the preset power distribution ratio, and obtains the first output power and the second output power.

For example, the terminal sets the first preset ratio to 10, the power distribution ratio to 10, and the total power to 11W, and the calculated signal power ratio of the GSM signal (the first signal) and the NB-IoT signal (the second signal) is 1:0.1= 10, then according to 10:1, the total power 11W is distributed, and the first output power is 10W and the second output power is 1W.

The second way is: when the terminal determines that the signal power ratio is lower than the first preset ratio and higher than the second preset ratio, calculate the product of the first signal power and the preset multiple, and use the product as the first output power, and calculating the product of the second signal power and the preset amplification factor, and using the product as the second output power.

For example, the terminal sets the first preset ratio to 10, the second preset ratio to 1, and the preset magnification to 5, and the calculated signal power ratio of the GSM signal (the first signal) and the NB-IoT signal (the second signal) is 2:1=2, and it is determined that 2 is within [1, 10], then the power of the GSM signal (the first signal) and the NB-IoT signal (the second signal) are amplified by 5 times, that is, the first output power is 2 *5=10W, the second output power is 1*5=5W.

The third method is: when the terminal determines that the signal power ratio is not higher than the second preset ratio, calculates the product of the preset maximum amplification factor and the second signal power, uses the product as the second output power, and calculates the total power and the second output power, and use the difference as the first output power.

For example, the terminal sets the second preset ratio to 1, the total power is 20W, the maximum amplification factor is 10, and the signal power ratio of the GSM signal (the first signal) and the NB-IoT signal (the second signal) is calculated as 1:5= 0.2, and it is determined that 0.2 is less than 1, then it is determined that the second output power is 1*10=10W, and the first output power is 20-10=10W.

Optionally, the first preset ratio may be 10, the second preset ratio may be 1, the total power may be 20W, and the maximum magnification may be 10.

The total power can be adjusted correspondingly according to the magnitude of the first signal power and the second signal power, so that when the first signal power and the second signal power are small, a larger total power can be used to perform signal processing on the signal. Supplement, conversely, choose a smaller total power.

Step 103: The terminal performs preliminary adjustment on the obtained first output power and second output power based on the preset maximum magnification.

Specifically, first, the terminal calculates an amplification ratio between the second output power and the second signal power.

Then, when the terminal determines that the acquired amplification ratio value is higher than the maximum amplification factor, it calculates the product of the maximum amplification factor and the second signal power, adjusts the second output power to the product, and calculates the total power and the adjusted second output power the difference, and adjust the second output power to the difference.

Further, if the acquired magnification is not higher than the maximum magnification, the terminal does not adjust the first output power and the second output power.

In this way, the amplification factor of the power of the signal can be guaranteed to be limited, and the situation where the amplification factor is too large can be avoided.

Step 104: The terminal adjusts the acquired first output power and second output power again based on the preset maximum power value.

Specifically, first, the terminal determines whether the received wireless signal is an uplink transmission signal, and if so, sets the maximum power value to the preset maximum uplink power value, otherwise, sets the maximum power value to the preset maximum downlink power value.

Optionally, the maximum uplink power value may be 1W, and the maximum downlink power value may be 10W.

In this way, the amplified maximum power value of the wireless signal can be adjusted according to the uplink transmission signal and the downlink transmission signal.

Then, when the terminal determines that the acquired second output power is higher than the maximum power value, the terminal adjusts the second output power to the maximum power value.

Finally, the terminal calculates the difference between the total power and the maximum power value, and adjusts the acquired first output power to the difference.

In this way, the maximum value of the amplified power of the wireless signal can be limited, so as to avoid the problem that the power of the signal is too large, causing loss to the device and reducing the success rate of the communication service.

Step 105: The terminal amplifies the power of the first signal to the adjusted first output power, and amplifies the power of the second signal to the adjusted second output power.

In this way, the first signal and the second signal can be distinguished by analyzing the bandwidth of the wireless signal, which reduces the cost of signal analysis and improves the efficiency of signal analysis. Further, according to the power of the first signal and the second signal The signal-to-power ratio of power assigns corresponding power to the first signal and the second signal, and limits the amplified power value through the maximum amplification factor and the maximum power value, thereby realizing different amplification of different signals.
