1. A sideband suppression method performed at a computer device, the method comprising:
obtaining a target baseband signal and a target signal correlated parameter corresponding to the target baseband signal, the target signal correlated parameter comprising at least one of a signal feature parameter corresponding to the target baseband signal or a signal feature parameter of a carrier signal corresponding to the target baseband signal;
obtaining a corresponding target sideband suppression parameter according to the target signal correlated parameter, the target sideband suppression parameter being used for suppressing a power of a first suppression sideband corresponding to the target baseband signal;
obtaining an initial compensation signal corresponding to the target baseband signal;
obtaining a target compensation signal according to the target sideband suppression parameter and the initial compensation signal;
correcting the target baseband signal based on the target compensation signal to obtain a target corrected baseband signal to obtain a target corrected baseband signal; and
inputting the target corrected baseband signal to a modulator for signal modulation, to obtain a target modulation signal corresponding to the target baseband signal.
