摘    要:分析了统计独立不同分布的Nakagami-m衰落信道下, 采用译码转发的多节点侦听单中继转发的机会中继系统的性能.推导了任意中继数目下接收端信噪比(SNR)的矩生成函数的闭合表达式,在此基础上得出了系统的中断概率和误符号率(SER)的闭式解. Monte Carlo仿真验证了理论分析的正确性.该闭式解可以用于评估机会中继系统在Nakagami-m信道下的性能,为实际工程提供理论参考.

关 键 词:通信技术  协作分集  机会中继  中断概率  误符号率  译码转发

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.
Keywords:communication  cooperative diversity  opportunistic relaying  outage probability  symbol error rate (SER)  decode-and-forward
