Title:
PREDISTORTION METHOD AND SYSTEM, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/244236
Kind Code:
A1
Abstract:
Disclosed are a predistortion method and system, a device, and a storage medium. The method is applied to the predistortion system. The predistortion system comprises a predistortion multiplier, a complex neural network, and a radio frequency power amplification output feedback loop. The method comprises: inputting a complex vector for training into the predistortion system to obtain a complex scalar corresponding to the complex vector for training output by the predistortion system; training the predistortion system on the basis of the complex vector for training and the complex scalar until a generalization error vector magnitude and a generalization adjacent channel leakage ratio corresponding to the predistortion system reach set requirements; and inputting a service complex vector into the trained predistortion system to obtain a complex scalar subjected to predistortion correction.
