| 摘 要： | 本文研究采用两条支路最大比合并(MRC)或选择合并(SC)分集接收的相关瑞利衰落信道理论容量推导恒定发射功率自适应M进制正交幅度调制(M-QAM)的频谱效率,并将它们与独立同分布瑞利信道理论容量进行比较,其结果对收发信机之间无视距分量路径、接收机上分集天线之间的距离小于半个波长的无线通信系统设计具有指导作用.

| Abstract: | Closed-form solutions for the correlated Rayleigh fading channel capacity under maximum ratio combining(MRC)or selection combining(SC)diversity reception are obtained in this paper.A comparison between the correlated Rayleigh fading channel capacity and independent Rayleigh fading channel capacity is presented.The performance of constant-power adaptive M-ary quadrature amplitude modulation (M-QAM) schemes over correlated Rayleigh channels under MRC or SC diversity reception is investigated.Closed-form expressions for spectral efficiency assuming perfect channel estimation and negligible time delay are derived. |

| Keywords: | correlated rayleigh fading channel channel capacity diversity reception maximal ratio combining (MRC) selection combing (SC) |
