Title:
SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/020283
Kind Code:
A1
Abstract:
Provided in the present application are a signal processing method and apparatus, comprising: for M signal components of a first signal, by means of unitary matrix processing by a baseband processing unit, allocating one signal to multiple feed channels for procedures such as modulation and power division; on an antenna unit by means of a bridge circuit having an inverse transform relationship to the unitary matrix, converging the signals of the multiple feed channels to a preset antenna, thereby implementing communication with a terminal device; the present invention can implement power sharing between feed channels of a remote radio unit without adding feed channels, and also implements flexible allocation of power between multiple antennas, reducing cost overheads.
