FEEDBACK METHOD FOR INTERFERENCE ALIGNMENT IN WIRELESS NETWORK

摘要

A feedback method for interference alignment in wireless network having K transmitters and K receivers is provides. The method comprising : transmitting, performed by transmitter n-1, a precoding vector of transmitter n-1 (n is a integer between 2 and K-1) to receiver n+1; calculating, performed by the receiver n+1, a precoding vector of transmitter n using the precoding vector of transmitter n-1; and transmitting, performed by the receiver n+1, the precoding vector of transmitter n to transmitter n.
