| 摘 要： | 针对多中继侦听单节点译码转发的机会中继系统,分析了其在统计独立不同分布的Nakagami-m衰落信道下的理论性能.基于接收端信噪比的矩生成函数的闭合表达式,推导了任意中继数目下系统中断概率和误符号率的闭式解,并通过仿真验证了其正确性.该闭式解可用于评估机会中继系统在Nakagami-m衰落信道下的性能,为实际工程应用提供理论参考.

| Abstract: | Closed-form expressions for the outage probability and symbol error rate of uncoded decode-and-forward cooperative systems with opportunistic relaying at arbitrary signal to noise ratios and number of available relays under independent but non-identical Nakagami-m fading channels were derived based on Moment Generating Function. Monte Carlo simulations were performed to corroborate the analysis. These expressions can be used to evaluate the performance of opportunistic relaying in Nakagami-m fading environment and used as the theoretical references for practical projects. |
