Free registration required

Executive Summary

In this paper, the authors investigate the performance of a dual-hop amplify-and-forward relay system in Nakagami-m fading channels in the presence of multiple interferers. Based on the new closed-form expression for the cumulative distribution function of a new type of random variable involving a number of independent gamma random variables, they present closed-form expressions for the outage probability, general moments for the end-to-end signal to interference and noise ratio and ergodic capacity of the system. In addition, they look into the high signal to noise ratio regime and characterize the diversity order and coding gain achieved by the system.
