摘    要:利用维希特随机矩阵理论和矩生成函数方法,推导了有信道估计误差的独立瑞利衰落信道上采用多输入多输出(MIMO)最大比合并(MRC)天线分集方案的矩形M进制正交幅度调制(MQAM)的平均误符号率(SER)解析表达式。数值计算结果阐明了信道估计误差和收发天线数对矩形MQAM调制MIMO MRC系统误码性能的影响。

关 键 词:正交幅度调制  最大比合并  误符号率  信道估计误差  多输入多输出系统

Abstract:By using Wishart random matrix theory and the moment generating function-based analysis approach,the exact closed-form expressions for the average symbol error rate (SER) of rectangular M-ary quadrature amplitude modulation (MQAM) multiple-input multiple-output (MIMO) maximal-ratio combining (MRC) systems with channel estimation error in independent and identically distributed Rayleigh fading channels are derived. Numerical results show the effects of channel estimation error and the number of transmit and receive antennas on the average SER of MIMO MRC systems with rectangular MQAM.
Keywords:quadrature amplitude modulation(QAM)  maximal-ratio combining(MRC)  symbol error rate(SER)  channel estimation error  multiple-input multiple-output system
