This paper introduces an efficient method for predicting mobile signal reception in satellite communications. The radio wave propagation between a satellite and a land receiver leads to two kinds of fading: slow-fading due to shadowing effect and fast-fading due to multipath effect. In order to model these fluctuations in the received signal and take into consideration the local area specificities, this paper propose a novel approach combining statistical and deterministic properties of radio propagations. For slow-fading, we use an efficient estimation of the local mean based on signal's coherence distance; for fast-fading, the principal parameter of Nakagami-m model can be estimated according to multipath nature, i.e., combination of electromagnetic interactions (reflections and diffractions) between radio wave and environment. The simulations in urban scenarios are based on Ergospace software.
