Abstract

This paper investigates the performance of a dual-hop amplify-and-forward relaying system with co-channel interference at the relay. The source node is equipped with multiple antennas and adopts the space-time block code to increase the diversity gain. Both the outage probability and the bit error rate in the presence of multiple Rayleigh fading interferers are obtained in closed-form. Simulation experiments are conducted to verify the theoretical derivations.
