| Abstract: | 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. |
