Performance Analysis of Optimal Beamforming in Relay-enhanced Wireless Communication Systems

  • 摘要: 考虑一对多天线的信源信宿通过一个单天线的放大前传(AF)中继辅助通信的两跳半双工无线网络。假设通信终端完全获知信道状态信息(CSI)。该文提出了该中继系统的最优波束成型方案,然后对采用此方案时的系统接收信噪比作高SNR下的统计特性分析,推导出瑞利平衰落信道下系统的遍历容量上界和平均误符号率(ASEP)的闭合表达式,并得出相应的分集度和阵列增益。理论分析结果显示了系统性能与天线数和发射功率的确切关系,并且在高SNR时不同的调制方式不影响分集度,只改变阵列增益。蒙特卡罗(Monte Carlo)数值仿真结果验证了理论分析的正确性。
