It can be understood that the signal receiver in this embodiment 4 is mainly some wireless communication devices, which may be specifically products capable of performing wireless communication, such as a mobile phone, a tablet computer, and the like. The signal receiver can receive some request signals sent by the antenna, and the signal receiver can determine the type of the received radio frequency signal according to the request signals. Therefore, in order to better receive the radio frequency signal, it is necessary to determine the type of the radio frequency signal to be currently received, after the type is determined, the corresponding radio frequency signal processing protocol is matched, and the radio frequency signal is received according to the matched radio frequency signal processing protocol, so that the communication efficiency of the wireless communication device can be improved, after the radio frequency signal is received, a target radio frequency band to which the radio frequency signal belongs also needs to be determined, because the wireless communication device performs analysis processing according to the received radio frequency signal when the user uses the wireless communication device, for example: comparing the waveform amplitude, the phase amplitude and the like of the radio frequency signal with the previously classified radio frequency signal types, determining a target frequency band to which the radio frequency signal belongs by the comparison difference value being small or similar, so as to make better adjustment for subsequently and continuously receiving the radio frequency signal, after obtaining the target radio frequency band, inquiring some mapping relation tables stored before according to the target radio frequency band, searching control parameters obtained by historical experience in the mapping relation tables, thus being capable of timely determining whether the currently received radio frequency signal has errors or low receiving rate so as to continuously solve the problem when the subsequently and continuously receiving is caused, therefore, adjusting the frequency of receiving the current radio frequency signal according to the control parameters, simultaneously calculating the error rate and the intensity index of receiving the radio frequency signal at the current moment, and finally adjusting the rate of receiving the current radio frequency signal according to the frequency, the error rate and the intensity index, so as to realize the speed adjustment of the wireless communication system receiving the radio frequency signal.
Optionally, in this embodiment 4, the querying, according to the target radio frequency band, the pre-stored mapping information, and determining the control parameter corresponding to the target radio frequency band includes:

According to different strength index levels and error rates, different receiving frequencies can be adjusted to improve the rate of receiving the current radio frequency signal.
In the method of this embodiment 4, by determining the type of the radio frequency signal to be received, and correspondingly receiving the radio frequency signal according to different types and using different radio frequency signal processing protocols, the efficiency of receiving the radio frequency signal in communication can be improved, thereby avoiding the phenomenon that the radio frequency signal is interrupted in the receiving process due to different protocols, and determining the target radio frequency band to which the radio frequency signal to be received belongs, and then determining the corresponding control parameter according to the target radio frequency band, so as to adjust the frequency of receiving the current radio frequency signal by using the control parameter, and the control parameter is obtained by detecting a plurality of frequency bands corresponding to the target radio frequency band in the mapping information, calculating a plurality of frequency deviations of the plurality of frequency bands corresponding to the target radio frequency band, and determining the corresponding control parameter according to the deviation value, and performing control by using the determined control parameter, the deviation value of the received radio frequency signals can be reduced, the accuracy rate of the received radio frequency signals is improved, and in addition, different receiving frequencies can be adjusted according to different intensity index levels and error rates so as to improve the rate of receiving the current radio frequency signals.
