Abstract
A signal processing method and apparatus, and a communication system, and relates to the field of communication technologies. The method includes: a processing unit of a first device first determines a distortion parameter of an eye pattern of a first PAM-N signal transmitted by a transmitting unit in the first device, then performs anti-distortion preprocessing on a second PAM-N signal using an equalizer based on the distortion parameter, to obtain a third PAM-N signal, and controls the transmitting unit to transmit the third PAM-N signal. The distortion parameter is for reflecting a tilt status of the eye pattern, and N≥2. The equalizer is used to perform anti-distortion preprocessing on the second PAM-N signal to obtain the third PAM-N signal.
