On the multi-state modeling of mobile satellite channels

We obtain new analytical expressions for the probability density function (PDF) of the received signal envelope in a mobile satellite channel. These expressions are derived from measured data for an urban environment, but the method can yield an insight into other environments. Using the average fade duration (AFD) and level crossing rate (LCR) data, we obtain a composite model, which is similar to other models given in the literature, e.g., the Loo (1985) model. This new model is amenable to the development of computer simulations of mobile satellite channel amplitude time series realizations, and provides additional insight into the physical channel character
