Abstract

A method, and an apparatus, for self-interference suppression in a relay for wireless communication, wherein the relay is arranged for receiving a signal r(n) transmitted from a transmitter, and for transmitting a self-interference suppressed transmit signal xr(n) to a receiver. The self-interference suppressed transmit signal xr(n) is achieved by determining a receive suppression filter matrix Wr, determining a relay amplification matrix G, and determining a transmit suppression filter matrix Wt, and then applying the suppression filters and the amplification matrix to the received signal r(n).
