Multiple-Source Multiple-Relay Cooperation System

In this paper, we study the multiple-source multiple-relay cooperation system. In the transmission protocol we proposed, the relay nodes not only decode and forward the symbols from the source nodes, but also encode the incoming symbols according to the cooperative code, resulting in higher efficiency and flexibility compared with previous repetition-coded cooperation system. We analyze the impact of the noisy interuser channel between the source nodes and the relay nodes on the system performance, and then propose an adaptive cooperative coding scheme to compensate for it. The analysis and the simulation results show that the proposed system achieves full diversity.
