提出了一种简单的机会放大转发（AF）中继的双向中继信道，其中两个节点希望在中继节点的帮助下以相同的传输速率彼此交换信息。特别地，可以以仅需要本地信道知识的分布式方式选择机会中继。结果表明，机会AF中继是outage-optimal单中继选择方案，并显着优于AF策略的基础上，等功率多中继传输与本地信道知识。数值和仿真结果验证了分析的正确性。
Presented is a simple opportunistic amplify and forward (AF) relaying for the two-way relay channel, where two nodes want to exchange information with each other at the same transmission rate with the help of relay nodes. In particular, the opportunistic relay can be selected in a distributed manner requiring only local channel knowledge. It is shown that opportunistic AF relaying is outage-optimal among single relay selection schemes and significantly outperforms an AF strategy based on equal-power multiple-relay transmission with local channel knowledge. Numerical and simulation results verify the analysis.
