摘　　要：该文研究了Nakagami信道上采用组合发送选择合并/接收最大比合并天线分集的M进制正交信号的误码性能。使用矩生成函数方法,推导了M进制正交信号的平均误比特率的近似解析表达式。该表达式可用于研究正交信号的维数、收发天线数对SC/MRC天线分集系统误码性能的影响,避免了耗时的计算机模拟。In this paper,the bit error performance of the M-ary orthogonal signals in conjunction with transmit selection combined with receive maximum ratio combining over Nakagami fading channels.Using the moment-gen-erating function approach,we derive the approximated average bit error rate expression for M-ary orthogonal sig-nals.It can be used to study the impact of the dimensionality of the orthogonal signals and the number of transmit/ receive antennas on the error performance of the SC/MRC antenna diversity sy...
