摘要
The model assumes that the amplitude of the line-of-sight component under foliage attenuation (shadowing) is lognormally distributed and that 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. This is true for both light and heavy shadowing.
