摘要 推导恒定发射功率下采用最大比合并分集接收的相关Nakagami衰落信道理论容量,并将它们与独立、同分布Nakagami衰落信道理论容量进行比较。研究相关Nakagami衰落信道上恒定发射功率自适应M进制正交幅度调制的频谱效率。数值计算结果阐明天线阵结构和衰落参数对Nak-agami衰落信道容量和自适应M进制正交幅度调制频谱效率的影响。 Closed - form solutions for the correlated Nakagami fading channel capacity with an average power constraint under maximum ratio combining diversity reception are obtained. A comparison between the independent fading channel capacity and correlated Nakagami fading channel capacity is presented. The performance of the spectral efficiency for constant- power adaptive M - ary quadrature amplitude modulation schemes over correlated Nakagami fading channel under maximum ratio combining diversity reception is investigated. Results show the effects of the antenna configurations and the fading parameter on the Nakagami fading channel capacity and the spectral efficiency of adaptive M - ary quadrature amplitude modulation.
