Relay selection scheme for two-way multi-relay communication system

Abstract

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.
