This paper 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 authors also resort to a well-known bounding technique to derive closed-form formulas for the upper and lower bounds for the MGF of dual-hop CAF relayed path SNR in Rice and Nakagami-m channels (since, exact evaluation of the MGF of half-harmonic mean SNR in Rice fading is known to be very complicated and numerically unstable).
