A channel model for nongeostationary orbiting satellite system

This paper introduces a channel model for land mobile satellite communication that is a combination of Rice and log-normal statistics, with independent shadowing affecting each direct and diffuse component, respectively. This model extends the channel model of a combined Rice and log-normal, proposed by Corazza (1994), to include the independent shadowing. The validity of the model is confirmed by comparisons with the data collected in the literature (the analytical model and the computer model) in terms of probability distribution of the envelope of each model. The model turns out to be one of many well-known narrowband models in limiting cases, e.g. Rayleigh, Rice, log-normal, Suzuki, Loo, and Corazza
