A generalized Rice channel for modeling mobile satellite link

In this paper, a land mobile satellite model is presented. The new model is obtained by extension for the Hoyt model by adding to the received signal a light of sight component (LOS); this new model is the generalized Rice fading. Expressions of the probability density function (PDF) of level crossing rate (LCR) and average fade and no fade duration (AFD, ANFD) are given. Comparisons between results calculated from the model to simulations show reasonably good agreements. The generalized Rice model should be useful for designing of communications systems in light-shadowing environments.
