Title:
PRE-DISTORTION PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/166534
Kind Code:
A1
Abstract:
A pre-distortion processing method and apparatus. The method comprises: obtaining a first continuous timing signal comprising a timing signal to be processed (S201); performing normalization processing on the first continuous timing signal to obtain a corresponding second continuous timing signal (S202); and inputting the second continuous timing signal into a pre-trained back propagation (BP) neural network model, and outputting a pre-distorted timing signal corresponding to the timing signal to be processed (S203), wherein the BP neural network model is an inverse behavior model of a corresponding target power amplifier (PA). Using the inverse behavior model based on the BP neural network, and performing normalization processing on the timing signal inputted into the model can better improve the non-linear factor of an overall system and improve the precision of pre-distortion processing.
