Performance Analysis of Decode-and-forward Transmission with Relay Selection in Mixed Fading Channels

  • 摘要: 蜂窝中继通信中基站到中继以及中继到移动台可以建模成混合衰落信道,即基站到中继的信道通常经历莱斯衰落,中继到移动台的信道通常经历瑞利衰落。该文研究混合衰落信道下协同通信系统中两跳译码转发方式的性能,首先通过分析推导了基于选择最佳中继的中断概率、误符号率以及误符号率的渐近线的闭式表达式,然后基于误符号率的渐近线给出了一种功率优化方法。蒙特卡洛仿真验证了理论公式,仿真结果显示优化功率分配的性能优于平均功率分配的性能。
