| 摘 要： | 从物理层安全的角度出发，在含有协作中继的通信网络中，通过选择最优中继来传递信息可有效提升系统性能。讨论了在含有多个单天线窃听用户的多中继通信系统中对最优中继的选择方案，并对系统采用放大转发（amplify-and-forward，AF）协议和解码转发（decode-and-forward，DF）协议这两种不同的情况分别进行了讨论和比较，同时还对比了不含中继的直接传输情况。理论分析和仿真结果表明，最优中继选择方案可有效保障系统的安全性能。

| Abstract: | Optimal relay selection can effectively improve the system performance in the communication network with cooperative relays from the view of physical layer security.The optimal relay selection schemes for relay transmission system with multiple single-antenna eavesdroppers were investigated,and the differences between the amplify-and-forward (AF) protocol and the decode-and-forward (DF) protocol were we discussed and compared separately.For comparison,the direct transmission without relay was also discussed.The theoretical analysis and simulation results show that the optimal relay selection scheme can effectively guarantee the security of the system. |
