Keywords: κ-μ fading channels | channel capacity | maximal ratio combining | optimal power and rate adaptation policy | constant transmit power policy

Analysis of channel capacity per unit bandwidth of L - branch maximal ratio combining (MRC) receiver operating over κ-μ fading channels for two adaptive transmission schemes is presented in this paper. Using the proposed system model, the optimal power and rate adaptation and constant transmit power policies are analyzed. New expressions for capacity evaluation are derived in terms of finite sums. The effects of diversity order and fading parameters on the channel capacity for given techniques have been considered and numerically presented.
