Abstract :
In this letter, we investigate the outage performance of a two-hop fixed-gain relay system in the presence of multiple unequal-power Rayleigh interference at both relay and destination. The closed-form expression for the outage probability is derived. We also show that the equal-power interference at the relay and destination leads to the worst outage performance.
