Abstract

In GEO satellite mobile communication system, a line-of-sight (LOS) component exists as well as multipath component, which are influenced by buildings or foliage that causing shadowing effect. Satellite mobile channel is described as fading model based on Markov process for channel properties in large circumstance. In this paper, a fading channel model based on three-state semi-Markov process is analyzed which several common models are taken into consideration. For received signals, multipath fading, shadowing effect and Doppler shift need to be discussed. This model is built on Rician model, Rayleigh model and C.Loo model, the probability density function (PDF) statistical properties are given, the functions of CCDF, LCR and ADF are derived. Simulation results suggest that this model switches among the three states obeying semi-Markov process, it sufficiently reflexes the merits of mixed channel model, provides an important meaning for channel actual tests.
