Abstract

In this paper, we consider the two-hop MIMO interference network, where T source-destination pairs communicate via T×K relays selected from G alternative relays. Based on optimal relay selection, each source-destination pair selected K relays to transmit data streams. In the first time slot, the source node transmits data steams to the selected relays by adaptive beam forming. In the second time slot, the selected relays forward the data streams by interference alignment technique. Compared the beam forming and interference alignment transmission mechanism based on fairness relay selection, our scheme can achieve higher system capacity.
