Abstract :
An improved Markov model for Rayleigh fading is proposed. Such a system considers both the amplitude and the speed of the fading envelope which jointly represent the Markov state. By properly selecting the state space size, proper fitting between the proposed system and Jakes´ Rayleigh fading simulator has been obtained. Further simulations, using a simple Go back N protocol, confirm the good throughput match between Jakes´ and the proposed Markov generators, not obtainable with classic one-dimensional models
