Abstract
In order to extend the network life on the base of lower Symbol Error Rate (SER),a relay selection scheme based on Hybrid Decode-Amplify-and-Forward(HDAF) relaying method is proposed.Joint optimization function about receiving Signal to Noise Ratio(SNR) at the destination and network life is defined to select the optimal relay.For the given threshold SNR at the relay nodes,all relay nodes are divided into two types:forwarding signal by Amplify-andForward(AF) relaying method and forwarding signal by Decode-and-Forward(DF) relaying method.The receiving SNR at the destination for each relay node is calculated and the optimal relay is selected reasonably according to the joint optimization function.Simulation results show that under the same conditions,the proposed relay selection scheme,compared with the relay selection scheme based on AF relaying method,not only achieves much better performance in SER,but extends the network life,improves system performance.关键词
