摘　　要：在n-Rayleigh衰落信道下,研究了使用发射天线选择(TAS)和选择合并(SC)接收的多输入多输出(MIMO)系统的平均符号误码率(ASEP)和中断概率(OP)性能。基于矩生成函数(MGF)的方法,推导了TAS/SC系统在n-Rayleigh衰落信道上采用相移键控调制(PSK)、正交幅度调制(QAM)和脉冲幅度调制(PAM)等几种数字调制方式的ASEP的精确表达式。同时,也得到了OP的精确闭合表达式。在不同条件下对系统的ASEP和OP性能做了数值仿真,理论分析结果与仿真结果相吻合,验证了理论分析结果的正确性。The average symbol error probability(ASEP) and outage probability(OP) performances of the multiple-input multiple-output(MIMO)system using transmitting antenna selection(TAS)and selection combining(SC)are studied by means of n-Rayleigh fading channel. On the basis of moment generating function(MGF)approach,the exact ASEP expressions of TAS/SC system using phase shift keying modulation(PSK),quadrature amplitude modulation(QAM),and pulse amplitude modulation(PAM)in n-Rayleigh fading channel are derived. The exact OP closed expressions are obtained. The ASEP and OP performances of the system were simulated numerically under different conditions. The simulation result is identical with the theoretical analysis result. The corretness of the theoretical analysis result was verified.
