In this paper, we have investigated the marginal moment generating function (MMGF) for the correlated Nakagami-m fading channel by using maximal-ratio combining (MRC) diversity scheme at receiver for the computation of channel capacity for various adaptive transmission schemes such as: 1) optimal simultaneous power and rate adaptation, 2) optimal rate adaptation with constant transmit power, 3) channel inversion with flxed rate, and 4) truncated channel inversion with flxed rate. The efiects of diversity receiver as well as correlation coe-cients on all these transmission schemes are discussed and the channel capacity obtained using this proposed approach for all schemes is compared with reported literature.
