Analysis of Relay Selection Algorithm in Two-way Relay System

In order to enhance the total rate bidirectional AF (Amplify and forward) relay system and reduce system outage probability,this paper proposes a minimum outage probability relay algorithm MOP (minimum outage probability),and describes the existing two relay selection algorithms with an analysis of the performance indices (signal to noise ratio,outage probability,and channel capacity) of the communication system.The simulation results show that the proposed minimum outage probability relay selection algorithm can significantly reduce the system outage probability with the performance of improve total rate of the system close to that of the maximum capacity relay algorithm.
