This article investigates the efficacy of a novel moment generating function (MGF) based analytical framework for calculating the ergodic channel capacities of cooperative dual-hop amplify-and-forward (CAF) relay networks under three distinct source-adaptive transmission policies in Rice and Nakagamim fading environments.The proposed analytical approach relies on a new exponential-type integral representation for the logarithmic function with the optimal joint power-and-rate adaptation (when the channel side information is available at both the transmitter and the receiver) and the optimal rate-adaptation with a constant transmit power (when channel side information is available at the receiver only) policies.
