Abstract

The traditional three-node cooperative communication model is simple and feasible, but in the two-stage cooperative transmission process, relay nodes usually help source nodes forward data for free. It reduces the efficient spectrum utilization when the links are of different qualities. Based on the decode-and-forward(DF) cooperative protocol, this paper proposed a new cooperative forwarding scheme. It could improve the transmission rate of the system by using superposition coding. The scheme used the CSI to process the relay selection and power optimal allocation. In collaboration, relay nodes transmitted their own data by superposition coding while forwarding the data of source nodes. By flexibly adjusting the power allocation during superposition coding, the proposed transmission scheme could guarantee the transmission rate of the system. Simulation results show that the proposed scheme can effectively improve the transmission rate of the system.
