A New Analytical Approach to Estimate Fading in Mobile Communication System Design

This paperprovides a novel analytical platform for evaluating theessential second order statistical boundaries for fading in mobile communication for average fade duration (AFD) and levelcrossing rate (LCR) of Rayleigh, Rician and Nakagami fading channels. We derive new expressions for average LCR and AFD. We then model and computationally simulate the proposed method for Rayleigh, Rician and Nakagami channels and separately calculate the LCR and AFD for each channel by this approach. Simulated results obtained for all three channels show that the values of LCR and AFD calculated by using the proposed approach are much closer to actual simulated values than what conventional theoretical formulas deliver.
