Abstract

In this paper, we investigate the outage behavior of a dual-hop opportunistic decode-and-forward (DF) relay system with co-channel interference (CCI) at both the relay and the destination. The source-relay and relay-destination channels as well as the interferers' channels at both the relay and the destination nodes are assumed to follow Nakagami-m distribution. Exact closed-form expressions for the outage probability for both independent non-identically distributed (i.n.d.) and independent identically distributed (i.i.d.) cases of interferers' channels are derived in this paper. Furthermore, the system behavior at high SNR values is studied via deriving the asymptotic outage probability. Our finding suggest that the co-channel interferers do not reduce the diversity order of the system, instead, they degrade the outage performance by affecting the coding gain of the system. The accuracy of the analytical results are supported by Monte-Carlo simulations.
