　　How to improve the reliable performance of information transmission is a fundamental issue in wireless relay network.Following maximum ratio combining(MRC)at relay station(RS),a maximum rate(Max-Rate)based spatial channel pairing(SCP)is proposed to further improve the reliable performance of information transmission in relay networks and its approximate closed-form solution is derived.The combination of MRC and Max-Rate based SCP is called Max-Rate SCP plus MRC,which includes three steps: channel phase cancellation,MRC,and SCP.From our simulation and analysis,compared to existing distributed space-time block coding and coherent combining(CC)schemes without SCP,the proposed Max-Rate SCP plus MRC achieves appreciable improvements in symbol error rate for medium and high signal-to-noise ratio regimes due to the use of Max-Rate SCP.
