A Random Number Generator Based Software Channel Simulator for Land Mobile Satellite Channel
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 nonfrequency- selective fading but considers the effects caused by shadowing. For such a channel model, a software channel simulator is designed. The simulator 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 method, the RNG method can be realized precisely in engineering. Furthermore, the operating frequency band of the simulator is not restricted to any particular frequency band, for the random numbers used in the simulator are independent of frequency. The validity of the simulator is confirmed by comparing fading statistics from the analytical model and the measured data.
