摘要
Abstract
Antenna Selection(AS) has the advantages of simple implementation and good performance. The performance of AS in the relay networks with Amplify-and-Forward(AF) and Decode-and-Forward(DF) strategies is evaluated . The evaluation method is as following: the first time slot of the relay station adopts the Maximum Ratio Combining(MRC) algorithm and the second time slot selects the optimal channel which has the maximum channel gain for signal transmission. Simulation results show that the MRC plus AS can provide better information rate and Signal Noise Ratio(SNR) performance compared to the Distributed Space-Time Block Coding(DSTBC) plus Maximum Ratio Combining(MRC) or MRC plus MF. When Symbol Error Rate(SER)=10-3, the scheme in the DFbased relay network achieves a 1dB SNR gain over the scheme in the AF based network.关键词
