摘      要：User cooperation enables single antenna terminals to benefit from spatial diversity by partnering with other users to create a virtual transmit antenna array. A promising form of cooperation is called coded cooperation which integrates cooperation with channel coding, showing great performance gains. In this paper, we examine the performance of coded cooperation scheme in fixed relay system, where channel coding is employed between source and relay. Simulation results are presented and show that it is always providing better performance and a higher throughput compared to decode and forward protocol. In addition to the diversity advantage, coded cooperation is based on incremental redundancy and thus receives coding gain.
