| Summary: | The invention provides an AGC system and method based on a pulse width modulation signal, and belongs to the field of millimeter wave wireless communication, and the system comprises a control unit which is used for carrying out analog-to-digital conversion based on a constant intermediate frequency signal to obtain a PWM signal duty ratio and sending the PWM signal duty ratio to a gain control circuit, and the gain control circuit is used for carrying out gain control based on the PWM signal duty ratio, and the variable gain unit is used for obtaining the amplified intermediate frequency signal, obtaining a constant intermediate frequency signal based on the amplified intermediate frequency signal and the control voltage, and sending the constant intermediate frequency signal to the control unit. The technical problems that the response time is long, the number of devices is large, the adjusting precision is poor, and the algorithm requirement is high are solved.
