摘　　要：未来海上编队作战中,为有效解决参战单元多,指挥关系复杂,信息流通量大等问题,需要有一套可靠的通信系统做保障,由于双向多中继通信系统具有较高的频谱利用率和网络吞吐量,是协同通信领域的研究热点。研究了双向多中继通信系统的通用模型,改进了现有的分布式中继选择方案,通过与最优接收信噪比中继选择方案和已有分布式中继选择方案进行仿真对比,优化后的系统信道容量和中断概率与最优中继选择方案比较接近,且在中断概率和中继数量较少时,信道容量较已有的分布式中继选择方案均有所提升。In order to effectively solve the problems of many units involved in the war, complex command relations and large information flow in the future naval fleet battle, a set of reliable communication system is needed. Two-way multi-relay communication system have higher spectrum utilization and network throughput, and it is a research hotspot in the field of collaborative communication. This paper systematically studies the general model of two-way multi-relay communication system, optimizes the distributed relay selection scheme based on the existing research. Through simulation comparison with the optimal received SNR relay selection scheme, the optimized system channel capacity and outage probability are relatively close, and they are improved by simulation comparison with the existing distributed relay selection scheme.
