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。
By using the moment-generating function-based analysis approach, the average Bit Error Rates(BER) for Muhiresolution 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 (OS-TBC) are adopted respectively in sending and receiving. The numerical results show that the SC/MRC scheme has better perfor-mance of average BER than that of the OSTBC scheme under the same antenna configuration.
