An Elementary Study on Design of MIMO AF Relay System with Interference Cancellation

摘要

This study considers the weight design problem of two-hop MIMO AF (amplify and forward) multiple relay system in which source, relays and destination are equipped with multiple antenna elements. Assuming perfect CSI (channel state information), optimization methods are presented based on the maximum SNR (signal to noise ration) criterion for three different cases. Through computer simulations, the effectiveness, features and problems are investigated for each relaying strategy.
