Sideband suppression method and apparatus, computer device, and storage medium

A computer device, comprising a memory and a processor, the memory storing computer-readable instructions, the computer-readable instructions, when executed by the processor, causing the computer device to perform a plurality of operations including:

• 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.
