Abstract

Embodiments of the present invention provide an interference cancellation method and device, which relate to the communication field, provide a mechanism for canceling interference in a MIMO full-duplex system, and solve the problem that the existing full-duplex system is difficult to apply in the MIMO scene. The specific scheme is as follows: each channel of interference signal is reconstructed according to each channel of reference signal to obtain the reconstructed interference signal, and then the residual signal is obtained according to the reconstructed interference signal and the received signal, and the parameters required for the reconstruction of the interference signal are further obtained. The embodiment of the present invention is used to realize the application of the full-duplex system in the MIMO scene.

Description

technical field [0001] The present invention relates to the communication field, in particular to an interference cancellation method and device. Background technique [0002] In mobile cellular communication systems, wireless local area network (Wireless Local Area Network, WLAN), fixed wireless access (Fixed Wireless Access, FWA) and other wireless communication systems, the base station (Base Station, BS) or access point (Access Point, A P ), a relay station (Relay Station, RS) and a user equipment (User Equipment, UE) and other communication nodes generally have the ability to transmit their own signals and receive signals from other communication nodes. Because the attenuation of the wireless signal in the wireless channel is very large, compared with its own transmission signal, the signal from the communication peer reaches the receiving end. The signal is already very weak. For example, the power difference between the sending and receiving signal of a communication ...
