A new simple model for land mobile satellite channels

Abstract

In this paper we propose a new shadowed Rice model for land mobile satellite channels. In this model the amplitude of the line-of-sight is characterized by the Nakagami distribution. The model provides closed-form mathematically-tractable expressions for the fundamental channel statistics such as envelope probability density function and envelope-squared moment generating function. The model is very convenient for analytical and numerical performance prediction of complex narrowband and wideband land mobile satellite systems, with different types of uncoded/coded modulations, with or without diversity. Comparison of the new model with published channel data demonstrates the flexibility of the model in characterizing a variety of channel conditions and propagation mechanisms.
