Problems solved by technology

In these systems, in the existing wireless full-duplex technology, the wireless signal of each transmitting antenna in the MIMO scenario will be coupled to each receiving antenna, and the existing technology can only offset the self-interference of a single transmitting antenna or part of transmitting antennas. The efficiency of interference suppression is not high, and the interference signal in the full-duplex multi-antenna system cannot be effectively eliminated

Abstract

The embodiment of the invention provides a method, device and system for processing interference signals for eliminating the interference signals in a full-duplex multi-antenna system. The method comprises the following steps: receiving wireless signals, wherein the wireless signals comprise self-interference signals of a sending antenna, and the self-interference signals comprise a first self-interference signal and a second self-interference signal; conducting primary interference offset processing on the received wireless signals by using a first reference signal to eliminate the first self-interference signal; conducting secondary interference offset processing on signals subjected to the primary interference offset processing by using a second reference signal to eliminate the second self-interference signal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for processing interference signals. Background technique [0002] In wireless communication systems such as mobile cellular communication systems, wireless local area networks, and fixed wireless access, communication nodes such as base stations or access points, relay stations, and user equipment usually have the ability to transmit their own signals and receive signals from other communication nodes. Wireless full-duplex technology simultaneously receives and transmits on the same wireless channel. Theoretically, the spectral efficiency is twice that of the existing frequency-division duplex or time-division duplex technology. The premise of realizing wireless full-duplex is to avoid, reduce and eliminate the strong interference of the transmitted signal of the same transceiver on the received signal as much as possible, so that it will not affect ...
