Abstract

A two-state statistical channel model is proposed for predicting the propagation characteristics of Land Mobile Satellite Channel (LMSC) according to propagation scattering theory. The underlying channel model takes for granted non-frequency- selective fading but considers the effects caused by shadowing. For such a statistical channel model, a software simulation model is designed. The simulation model is based on a Random Number Generator (RNG) that generates data sets to compute fading statistics of the propagation channels. Compared with the filter method and the Rice sum of sinusoids method, the RNG method can be realized precisely in engineering. Furthermore, the operating frequency band of the simulation model is not restricted to any particular frequency band, for the random numbers used in the simulation model are independent of frequency. The validity of the statistical model and its corresponding simulation model is confirmed by comparing fading statistics from the simulation model and a classical analytical model.
