| 摘 要： | 分析了机会中继和最大比合并下的协作通信系统性能.首次给出了Nakagami衰落信道下的符号错误率和中断概率的精确闭式结果.通过对中断概率的近似结果分析发现对于任意一条源节点-中继-目的节点链路,分集增益均由源节点-中继链路和中继-目的节点链路中的深衰落链路决定.

| Abstract: | The performance of cooperative communication systems with opportunistic relaying and maximal-ratio-combining(MRC) was analyzed.Exact and closed-form expressions of symbol error rate(SER) and outage probability with Nakagami fading channels were firstly given.The analysis of approximate outage probability indicated that the diversity advantage was determined by the more severely fading channel out of the sonrce-relay channel and the relay-destination channel. |

| Keywords: | cooperative communication opportunistic relaying symbol error rate outage probability Nakagami fading channels |
