A statistical model for a land mobile satellite link

TLDR

The paper presents a statistical model for land mobile satellite links. The model assumes a lognormal line‑of‑sight amplitude under foliage shadowing and Rayleigh multipath, and derives expressions for level crossing rate and average fade duration. Model predictions agree well with measurements and are useful for designing satellite communication systems and simulating propagation.

Abstract

A statistical model for a land mobile satellite link is described. The model assumes that the amplitude of the line-of-sight component under foliage attenuation (shadowing) is lognormally distributed and the received multipath interference has a Rayleigh distribution. Expressions for the level crossing rate and average fade duration are given. Comparison between results calculated from the model and from measurements show reasonably good agreement. The model should be useful for designing communications systems and for simulating propagation effects in the laboratory.
