A cooperative communication scheme based on PDA+LDPC iterative detection algorithm

This paper investigates the performance of the iterative receivers for the synchronous DS-CDMA cooperative communication system,which employs PDA + LDPC iterative detection algorithm at both the cooperative partner node and the base node.Furthermore, it presents a central-controlled cooperative partner node selection scheme by employing the information provided by the iterative receivers.With the presented scheme,every source node takes the priority to select the node which is nearer from the base node as its cooperative node for its better communication ability with the base node.Simulation results demonstrate that the proposed scheme can achieve some better performance.
