Abstract - The distribution of the local average power at a mobile is usually considered to be
lognormal in terrestrial and satellite channels. However, the mathematical form of the lognormal
distribution is not convenient for analytic calculations. In this paper, we show the utility of the
gamma distribution for shadow fading, in both terrestrial and satellite channels, using empirical
data. Furthermore, we show that the application of the gamma model of shadow fading results in
closed-form and mathematically-tractable solutions for key system performance measures such
as the average symbol error rate of different modulations with a variety of diversity combining
techniques.
