Abstract :
In this paper we analyze the effect of co-channel interference on the performance of cooperative decode-and-forward (DF) automatic-repeat-request (ARQ) scheme under Rayleigh fading channels. We assume that the relay node is affected by one interferer and the destination node is affected by another one. The outage probability of the cooperative DF ARQ scheme is derived based on the maximal ratio combining (MRC) technique. The closed-form expression clearly shows the outage probability has much to do with the maximum number of ARQ transmissions. Finally, Monte Carlo simulation results verify our theoretical analysis.
