A Novel MGF Based Analysis of Channel Capacity of Generalized-K Fading With Maximal-Ratio Combining Diversity

Abstract

Abstract-In this paper, we have analyzed the channel capacity by using the maximal-ratio combing (MRC) diversity scheme for communication systems operating over a composite fading environment modeled by the Generalized-K distribution at the receiver. For the Generalized-K fading channel with arbitrary values for small and large scale fading parameters, we have derived a closed-form expression for the moment generating function (MGF) of the received signal-to-noise ratio (SNR) and utilized it to obtain a novel closed-form expressions for the channel capacity under different adaptive transmission schemes. The result of the proposed methods is compared with other reported literature to support the analysis.

“…The proposed approach in [15] takes advantage of alternative integral representations of the symbol error rate, along with Laplace transforms, to derive the SER expressions. In [16] authors presented a method based on moment generating function (MGF based method) to analyze the capacity of generalized K-fading channels with maximal ratio combining.…”
