摘要 对于任意抽头数的多输入多输出(MIMO)频率选择性Nakagami衰落信道,利用矩生成函数(MGF)方法和高斯Q函数的指数近似表达式,推导采用矩形M进制正交幅度调制(MQAM)的空频分组编码(SFBC)正交频分复用(OFDM)系统的平均误符号率(SER)性能的精确和近似解析表达式。数值计算和仿真结果证明了理论分析的正确性和近似分析的准确性。 For arbitrary-tap frequency selective multiple-input multiple-output（MIMO）Nakagami fading channels,we derive exact and approximate closed-form expressions for the average symbol error rate of space-frequency block coded（SFBC）-orthogonal frequency division multiplexing（OFDM）systems with rectangular M-ary quadrature amplitude modulation（QAM）by using moment generating function（MGF）based analysis approach and the exponential bounds for the Gaussian Q-function.Numerical and simulation results show that the theoretical analysis is exact and the approximate analysis is accurate.
