Outage probability of opportunistic decode-and-forward relaying with co-channel interferences

In this paper, we first derive an exact and closed-form outage probability of opportunistic decode-and-forward (DF) relaying when considering unequal-power co-channel interferences under the Rayleigh fading channels. Numerical results show that the analytical results obtained here are exactly matched with the simulated ones. When comparing to the results without interferer, we can see that the outage performances with interferers are saturated as increasing transmit signal-to-noise ratio (SNR).
