Abstract: This application provides example signal processing methods, media, and apparatuses. One example method includes obtaining a scattering parameter matrix of passive echoes in an antenna system by a network device. The m virtual user directions are determined by the network device based on the scattering parameter matrix of the passive echoes, where the m virtual user directions are m directions in which total signal strength of the passive echoes is highest, and m is a positive integer. A target beam is formed based on n real user directions and the m virtual user directions, where one or more nulls of the target beam are aligned with the m virtual user directions, n is a positive integer, and n+m≤k.

Abstract: The present disclosure relates to pre-distortion processing methods and apparatus. One example apparatus includes a first pre-distortion part and a second pre-distortion part. The first pre-distortion part includes N digital pre-distortion (DPD) processors. The first pre-distortion part and the second pre-distortion part perform pre-distortion processing on a signal to support a power amplifier in performing linear amplification on the signal.
