摘　　要：A novel relay selection criterion, in which the traffic-knowledge is utilized, is proposed for asymmetric two-way amplify-and-forward （AF） relaying networks. The system outage probability, diversity gain and coding gain are then investigated, and closed-form expressions are presented. Simulation results verify the accuracy of our derived outage probability expressions and highlight the performance of the proposed relay selection policy.A novel relay selection criterion, in which the traffic-knowledge is utilized, is proposed for asymmetric two-way amplify-and-forward （AF） relaying networks.
