Optimum Combining With Joint Relay and Antenna Selection for Multiple-Antenna Relays in the Presence of Co-Channel Interference
Navod Suraweera, Norman C. Beaulieu · IEEE Communications Letters · 2014
The performance of optimum combining (OC) with joint relay and antenna selection is analyzed for decode-and-forward relaying when co-channel interference is present at the relays and the destination. The combination of OC with joint relay and antenna selection results in positive diversity gains if at least one relay has Ti> Ni, where Tiis the number of relay antennas and Niis the number of interferers at the relay, when the interferer powers are scaled with the source and the relay powers.
