Abstract

In this paper, we introduce a more effective approach to analyze the envelope correlation property of two signals received at different carrier frequencies which contain multiple Rayleigh fading sub-clusters upon the noise influence, and propose a new approximate envelope correlation expression for maximal ratio combination (MRC), which may solves the difficulties occurred in analysis of signal correlation property under noise´s environment, these expressions generalize known analytical results obtained for the case of single sub-cluster. Simulation results demonstrate the effectiveness of the proposed approach.
