放大转发方式下中继选择策略的性能分析

摘要

研究了几种主要的协同中继选择策略;通过仿真对比了在放大转发方式（Amplifier-and-forward AF）下全部协同、部分协同、机会中继的中断概率性能;最后归纳总结了中继节点数目、信噪比及目标信息速率对上述中继选择策略中断概率性能的影响情况。%Based on the cooperative protocols that have been discussed,the article summarizes and compares the all-participate relaying,portion-participate relaying and opportunistic relaying,and discusses the target rate,the number of cooperative relays and SNR in the outage probability under Amplifier-and-forward（AF）.
