Rayleigh flat fading channel modeled as a G/HR/1 queue

In this paper we propose a queuing model for predicting behavior of an uncorrelated Rayleigh flat fading channel. Using the notion of Hyperexponential (HE) probability density function, we model a Rayleigh fading channel as a combination of a few parallel exponential processes in the form of G/HR/1 queue with well-defined service and waiting time distributions. We illustrate validity of our analytical model with some numerical results.
