Outage Probability of Opportunistic Relaying in Rayleigh Fading Channels With Multiple Interferers

In this letter, as multiple interferers have an effect on both the relays and the destination, the exact outage probabilities for the decode-and-forward (DF) opportunistic relaying are derived in three different cases: a) with selection combining (SC) deployed at the destination, b) with maximal ratio combining (MRC) deployed at the destination, and c) with hybrid selection and maximal ratio combining (HSMC) deployed at the destination. Simulation results validate our analysis, and show that in terms of outage probability, opportunistic relaying with HSMC is much better than that with SC or MRC.
