| 摘 要： | 使用矩生成函数方法分别推导了Nakagami衰落信道上多分辨率M进制正交幅度调制(MR-MQAM)的平均误比特率(BER)闭合表达式,发送和接收分别采用选择合并/最大比合并(SC/MRC)和正交空时分组编码(OSTBC).数值计算结果表明在相同的天线设置条件下,SC/MRC方案的平均误比特率性能要优于OSTBC.

| Abstract: | By using the moment-generating function-based analysis approach, the average Bit Error Rates(BER) for Multiresolution M-ary Quadrature Amplitude Modulation(MR-MQAM) in Multiple Input Multiple Output(MIMO) Nakagami fading channels is described.The schemes Selection Combined with Maximum Ratio Combing(SC/MRC) and Orthogonal Space-Time Block Coding(OSTBC) are adopted respectively in sending and receiving.The numerical results show that the SC/MRC scheme has better performance of average BER than that of the OS... |
