Abstract

In this paper, we investigate the impact of an arbitrary number of Rayleigh faded co-channel interferers with arbitrary powers on the performance of dual-hop transmission systems that employ amplify-and-forward relays. The received signals at the relay and destination undergo independent but not necessarily identical Nakagami-m fading. Analytical expressions for the exact and asymptotic outage probability and the average bit error probability of various digital modulation schemes are derived. The analysis quantifies the impact of channel parameters for the desired and interfering links on the performance of interference-limited dual-hop relaying systems. Various numerically evaluated and computer simulation results are presented to corroborate the proposed analysis.

瑞利干扰下双跳AF系统的精确渐近分析
在本文中,我们研究了任意数量、任意功率的瑞利衰减同信道干扰对采用放大转发中继的双跳传输系统性能的影响。在中继和目的地接收到的信号经历独立但不一定相同的中上米衰落。导出了各种数字调制方案的精确、渐近中断概率和平均误码概率的解析表达式。分析量化了期望链路和干扰链路的信道参数对限制干扰双跳中继系统性能的影响。给出了各种数值计算和计算机模拟结果来证实所提出的分析。
