APPARATUS AND METHOD FOR INTERFERENCE CANCELING IN MULTI-ANTENNA SYSTEM

摘要

PURPOSE: A method and an apparatus for removing interference in a multiple antenna system are provided to confirm the whitening property of an interference signal by using a covariance matrix of the interference signal. CONSTITUTION: A receiver estimates a channel(703). The receiver estimates a covariance matrix for an interference component and a noise(705). The receiver confirms whitening property of an interference signal(707). The receiver receives a diagonal loading factor(709). The receiver compensates the covariance matrix(711). The receiver generates a whitening matrix(713). The receiver performs whitening filtering of a channel estimation value(715).
