METHOD AND APPARATUS FOR RECEIVING SIGNAL IN WIRELESS ACCESS SYSTEM SUPPORTING FDR TRANSMISSION

摘要

The present invention relates to a wireless access system supporting a full duplex radio (FDR) transmission environment. A method for eliminating interference in a signal received by a first apparatus from a second apparatus in a wireless access system supporting FDR transmissions according to one embodiment of the present invention comprises the steps of: acquiring a matrix, H, for channels between the first apparatus and second apparatus by means of feedback information received from the second apparatus; acquiring information regarding a transmission signal, s, transmitted by the first apparatus; generating a reception filter matrix, G, by utilizing null-space basis vectors from among left singular vectors included in an effective interference matrix, Hs, generated by multiplying the matrix, H, and transmission signal, s; and eliminating self-interference corresponding to the transmission signal, s, from a desired signal received from the second apparatus by utilizing the reception filter matrix, G.
