In an embodiment of the present invention, the communication system includes a receiver system as a receiving side, and a Central Processing Unit (CPU), and the receiver system includes a receiving amplifier for performing a signal processing operation. The receiving performance optimization method of the communication system provided in the first embodiment of the present invention is executed by the central processing unit, specifically executed through steps S11 to S17:
s11, under the current communication turn, determining a corresponding signal level range according to the level of a signal frame sent by each communication device in the current communication environment.
It should be noted that the communication turn may be a division unit according to the application state of the communication system. By way of example, in a home communication environment, the communication system is a mobile communication device, and the home communication scenario includes several communication slave devices, such as a router.

If Pi _ max > Pmax is satisfied, indicating that the target operating parameters of the previous communication round are also applicable to the operating parameters of the receiving amplifier of the current communication round, directly calling the target operating parameters of the previous communication round, and controlling the receiving amplifier to operate under the target operating parameters.
If Pi _ max is less than or equal to Pmax, which indicates that the target working parameter of the previous communication round cannot be directly used as the working parameter of the receiving amplifier of the current communication round and needs to be subjected to fine adjustment, determining a corresponding adjustment step length according to the ratio of Pi _ max to Pmax, increasing the value of the target working parameter of the previous communication round acquired from the table, and using the value as the target working parameter of the receiving amplifier in the current communication round.
