The invention relates to an
interference elimination system and method based on pre-
equalization and belongs to the field of communication and
signal processing. At a receiving end, a received
signal is divided into two paths, one path
signal is sent to an
interference elimination self-adapting filter and serves as an input signal of the
interference elimination self-adapting filter, the other path signal is sent to a pre-
equalization computing module, weight is computed by the pre-
equalization computing module according to the received signal or a channel estimated value, and the computed weight is enabled to be sent to a pre-
equalizer of an interference emission end. At the interference emission end, an emission signal is divided into two paths, one path signal serves as a referential signal and is sent to the interference
elimination self-adapting filter at the receiving end, the other path signal is sent to the pre-
equalizer, and pre-equalization
processing is carried out on the emission signal by the pre-
equalizer and then the emission signal is sent out. Compared with a traditional interference
elimination method, the interference
elimination method is capable of simplifying work of the interference elimination self-adapting filter and effectively eliminating
broadband self-interference signals.
