Inter-channel linear crosstalk estimation method and apparatus and receiver

Abstract

An inter-channel linear crosstalk estimation method and apparatus and a communication system are disclosed. The apparatus includes: an adjacent channel synchronizing unit configured to synchronize adjacent channel information inserted with a cyclic training sequence in a received signal, to determine a time window of occurrence of the cyclic training sequence; a time domain cutoff unit configured to perform time cutoff on center channel information in the received signal according to the time window of occurrence of the cyclic training sequence, to obtain center channel information within the same time window as the cyclic training sequence; a filtering unit configured to filter the center channel information within the time window, and reserve center channel information containing linear crosstalk from an adjacent channel; and a linear crosstalk estimating unit configured to estimate a magnitude of linear crosstalk leaking into the center channel by using a cyclic characteristic of the cyclic training sequence.
