Abstract
In this paper, the performance of cooperative decode-and-forward (DF) automatic-repeat-request (ARQ) scheme with co-channel interference is investigated in a long-term static Rayleigh fading environment. We assume that the relay node is impaired by M interferers and the destination node is impaired by N interferers. A closed-form expression for the outage probability of cooperative DF ARQ scheme with co-channel interference is derived. Then we analyze the average throughput of the scheme with co-channel interference and further derive that the average throughput is mainly influenced by the interferers at the destination node. The average total power consumption per information packet of cooperative DF ARQ scheme with co-channel interference is investigated and a closed-form expression is obtained for cooperative DF ARQ scheme with co-channel interference, in which the source and relay may use different transmission power level in different transmission time slots. The closed-form expression is valid for any maximum number of transmission time slots L allowed by the protocol and may play a key role in optimizing power allocation. Numerical and simulation results are presented to verify our analysis.
