摘要
Abstract
The direct transmission(DT),fixed decode-and-forward(DF)relaying,selective DF relaying(SR)and incremental relaying (IR)protocols are studied over the single relay cooperative communication system model.In order to enhance the spectral efficiency and outage performance in cooperative communication system, an improved decode-and-forward ( IDF ) method is proposed. Whether the IDF method adopting the cooperative communication model or not bases on the comparison about the instantaneous channel gains of source-to-destination with that of relay-to-destination.Moreover,an incremental selection relaying(ISR)is proposed,combining the advantages of SR and IR.The outage probability expressions of the improved protocols at arbitrary SNR are also given in the paper.Simulation results show that,compared with traditional single relay DF,IDF and ISR have lower outage probability.And ISR has the lowest outage probability.关键词
