Referring to fig. 1, a schematic structural diagram of a GSM mobile terminal 100 according to an embodiment of the present invention is shown, where the GSM mobile terminal 100 includes a processor 110, a transceiver 130, a power amplifier 120, an antenna switch module 140, and an antenna 150, the processor 110 is electrically connected to the transceiver 130, the power amplifier 120, the antenna switch module 140, and the antenna 150 are electrically connected in sequence, and the antenna 150 is communicatively connected to a base station 200.
In this embodiment, the processor 110 is configured to send a control signal to the transceiver, and the transceiver 130 is configured to provide the control signal, the communication signal, and the clock signal to the power amplifier 120; the power amplifier 120 is configured to amplify the communication signal according to the control signal, and send the processed communication signal to the antenna switch module 140; the antenna switch module 140 transmits the processed communication signal to the base station 200 through the antenna 150, so as to implement communication between the GSM mobile terminal 100 and the base station 200. The processor 110 is further configured to adjust the transmission time of the control signal when the communication signal is not synchronized with the operation of the transceiver 130, the power amplifier 120, and the antenna switch module 140, so as to adjust the time interval between the operation of the transceiver 130, the operation of the power amplifier 120, and the operation of the antenna switch module 140, so that the power amplifier 120 amplifies the communication signal transmitted by the transceiver 130 according to the adjusted control signal. In the present embodiment, the communication signal transmitted by the transceiver 130 has too low power, and the antenna 150 cannot directly transmit the communication signal to the base station 200. The power amplifier 120 is required to amplify the communication signal so that the amplified communication signal has sufficient power to be transmitted to the base station 200 by the antenna 150. The processor 110 sends a control signal to the power amplifier 120 through the transceiver 130, so that the power amplifier 120 starts amplifying the communication signal according to the control signal and ends amplifying the communication signal according to the control signal.
The power amplifier 120 and the antenna switch module 140 may be integrated on a chip, for example, a chip of loda AP6716M-21 may be used. The GSM mobile terminal 100 may employ, but is not limited to, a GSM handset and a GSM tablet.
It should be understood that the structure shown in fig. 1 is only a schematic structural diagram of the GSM mobile terminal 100, and the GSM mobile terminal 100 may also include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Fig. 2 is a schematic flow chart of an interference signal processing method according to an embodiment of the present invention. It should be noted that, the interference signal processing method provided in the embodiment of the present invention is not limited by fig. 2 and the following specific sequence, and it should be understood that, in other embodiments, the sequence of some steps in the interference signal processing method provided in the embodiment of the present invention may be interchanged according to actual needs, or some steps in the interference signal processing method may be omitted or deleted. The interference signal processing method can be applied to the processor 110 of the GSM mobile terminal 100 shown in fig. 1, and the specific flow shown in fig. 2 will be described in detail below.
Step S101, a control signal is transmitted to a power amplifier through a transceiver.
And step S102, when the communication signal sent by the transceiver is asynchronous with the working actions of the transceiver, the power amplifier and the antenna switch module, adjusting the sending time of the control signal to adjust the time interval of the working action of the transceiver, the working action of the power amplifier and the working action of the antenna switch module, so that the power amplifier amplifies the communication signal sent by the transceiver according to the adjusted control signal and sends the processed communication signal through the antenna switch module.
In this embodiment, the control signal includes an enable start signal and an enable end signal, the power amplifier 120 starts amplification processing of the communication signal after receiving the enable start signal, and the power amplifier 120 stops amplification processing of the communication signal after receiving the enable end signal.
As shown in fig. 3, which is a power-versus-time diagram of the high-pass platform, when the power amplifier 120 starts to amplify a communication signal (i.e., when the power amplifier 120 receives an enable start signal), the power amplifier 120 starts to amplify the communication signal, and transmits the amplified communication signal to the base station 200 through the antenna 150 switch module and the antenna 150. And from pa _ en _ star point to pa _ star point is the rising edge of the amplified communication signal.
As shown in fig. 4, which is a power-versus-time diagram of the high-pass platform power amplifier 120 finishing amplification processing of the communication signal, the power amplifier 120 stops amplifying the communication signal from a pa _ en _ stop point, and stops transmitting the amplified communication signal to the base station 200 through the antenna 150 switch module and the antenna 150. And from the point pa _ stop to the point pa _ en _ stop is the falling edge of the amplified communication signal.
From pa _ en _ star point to pa _ en _ stop point, which is the whole time sequence process of the communication signal amplification process performed by the power amplifier 120, the clock signal may be transmitted from a certain time point, especially during the rising edge and the falling edge, because the process involves the switching point of transmission and reception, and thus belongs to the unstable state of the power amplifier 120 during the rising edge and the falling edge. Therefore, the isolation between the amplified communication signal and the clock signal in the power amplifier 120 can be increased by adjusting the sending time of the control signal, and the problem of spurious caused by clock signal leakage is solved.
In the present embodiment, when the time when the power amplifier 120 receives the communication signal is later than the time when the power amplifier 120 operates, the first predetermined time is delayed to transmit the enable start signal to the power amplifier 120, so that the operation of the transceiver 130 and the operation of the power amplifier 120 are synchronized with the communication signal. It can be understood that when the enable start signal is already sent to the power amplifier 120 and the communication signal is not yet sent to the power amplifier 120, if the antenna switch module 140 is in the on state, other signals such as the clock signal may be amplified by the power amplifier 120 and sent to the antenna 150 through the antenna switch module 140, and the antenna 150 may transmit other signals such as the clock signal to the base station 200, thereby causing the clock signal to leak. Therefore, the first preset time is delayed to transmit the enable start signal to the power amplifier 120, and the time point when the power amplifier 120 starts to operate is the same as the time point when the communication signal is received, so that there is no time interval between the time point when the power amplifier 120 starts to amplify and the time point when the communication signal is received, and no idle time interval leaks the clock signal, so that the spurious signal disappears.
In the present embodiment, the reason why the time when the power amplifier 120 receives the communication signal is later than the time when the power amplifier 120 operates may be that the actual time interval between the operation of the transceiver 130 and the operation of the power amplifier 120 is not consistent with the preset time interval. For example, the preset time interval between the operation of the transceiver 130 and the operation of the power amplifier 120 is 1S, that is, the communication signal sent by the transceiver 130 to the power amplifier 120 needs 1S of time for the power amplifier to receive; since the operation time of the transceiver 130 is delayed and the operation time of the power amplifier 120 is generated on time, the actual time interval between the operation of the transceiver 130 and the operation of the power amplifier 120 is less than 1S, and the transmission time of the communication signal from the transceiver 130 to the power amplifier 120 needs 1S to be constant, which results in the time for the power amplifier 120 to receive the communication signal being later than the operation time of the power amplifier 120.
The first preset time is the difference between the time when the power amplifier receives the communication signal and the time when the power amplifier works. That is, the time for the power amplifier 120 to receive the communication signal is 0.1S later than the time for the power amplifier 120 to operate, and the first predetermined time is 0.1S.
In this embodiment, when the time when the processed communication signal stops being sent to the antenna switch module is prior to the time when the enable end signal is sent to the power amplifier, the enable end signal is sent to the power amplifier in advance by the second preset time, so that the operation of the power amplifier and the operation of the antenna switch module are synchronized with the communication signal.
It can be understood that when the processed communication signal has stopped being transmitted to the antenna switch module 140 and the enable end signal has not been transmitted to the power amplifier 120, the transceiver 130 has stopped transmitting the communication signal to the power amplifier 120, but the power amplifier 120 does not receive the enable end signal, and the power amplifier 120 is still in an operating state, if the antenna switch module 140 is in an on state, other signals such as a clock signal may be amplified by the power amplifier 120 and transmitted to the antenna 150 through the antenna switch module 140, and the antenna 150 may transmit other signals such as the clock signal to the base station 200, thereby causing leakage of the clock signal. Therefore, the enable end signal is sent to the power amplifier 120 in advance by the second preset time, and the time point when the power amplifier 120 finishes amplifying the communication signal is the same as the time point when the enable end signal is received, so that there is no time interval between the time point when the power amplifier 120 finishes amplifying the communication signal and the time point when the enable end signal is received, and there is no idle time interval to leak other signals such as clock signals in the GSM mobile terminal 100, so that the spurs will disappear.
The second preset time is a difference between a time when the processed communication signal stops being transmitted to the antenna switch module 140 and a time when the enable end signal is transmitted to the power amplifier. That is, the time when the power amplifier 120 stops transmitting to the antenna switch module 140 is 0.1S earlier than the time when the power amplifier 120 receives the enable end signal, the second predetermined time is 0.1S.

In this embodiment, the adjusting module 162 is configured to delay the first preset time to send the enable start signal to the power amplifier 120 when the time when the power amplifier 120 receives the communication signal is later than the time when the power amplifier 120 operates, so that the operation of the transceiver 130 and the operation of the power amplifier 120 are synchronized with the communication signal.
In this embodiment, the adjusting module 162 is configured to send the enable end signal to the power amplifier 120 in advance by a second preset time when the processed communication signal stops being sent to the antenna switch module 140 before the enable end signal is sent to the power amplifier 120, so that the operation of the power amplifier 120 and the operation of the antenna switch module 140 are synchronized with the communication signal.
