摘要:

研究独立同分布Rayleigh衰落条件下采用选择解码转发协议的多点合作中继系统的误符号率和中断率性能. 文中采用矩母函数分析方法,通过引入超几何函数推导了Rayleigh衰落信道中多点合作通信系统的平均符号错误率和中断率的精确闭合表达式. 通过蒙特卡洛仿真验证了表达式的正确性,结果显示两跳多点合作中继通信系统比传统的合作系统性能更好.

关键词: 合作分集, 瑞利衰落, 选择解码转发, 超几何函数, 误符号率

Abstract:

The paper studies performance of multi-point relaying cooperative communication system using selection decode-and-forward relays over an independent and identically distributed Rayleigh fading channel. Closed-form expressions of average symbol error rate (SER) and outage probability (OP) in Rayleigh fading channels are derived using moment generating function (MGF) and hyper-geometric function. Compared with
the traditional cooperative communication system, performance of two-hop multi-point cooperative relayingcommunication systems is better.

Key words:  cooperative diversity, Rayleigh fading, selection decode-and-forward, hypergeometric function, symbol error rate
