Abstract
Disclosed are a predistortion method and system, a device, and a non-transitory computer-readable storage medium. The predistortion method is applicable to a predistortion system which may include a predistortion multiplier, a complex neural network, and a radio frequency power amplifier output feedback circuit. The method may include: inputting a training complex vector to the predistortion system to obtain a complex scalar corresponding to the training complex vector, which is output by the predistortion system; training the predistortion system based on the training complex vector and the complex scalar until a generalization error vector magnitude and a generalization adjacent channel leakage ratio corresponding to the predistortion system meet set requirements; and inputting a service complex vector to the trained predistortion system to obtain a predistortion corrected complex scalar.
