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. This paper theoretically analyzes the performances of opportunistic decode-and-forward relaying system with multi-relay in dependent but non-identical Nakagami-m fading channels.Based on the derived closed-form expressions for the moment-generating function of arbitrary signal-to-noise ratios,the closed-form expressions of the outage probability and the symbol error rate of the relaying system with arbitrary relays are obtained and further verified by simulation.The obtained closed-form solutions can be used to evaluate the performances of opportunistic relaying systems in Nakagami-m fading channels and provide theoretical references for practical engineering projects.
