A propagation model for land mobile satellite communications

Abstract

The author presents a land mobile satellite propagation model which includes multipath fading and shadowing effects. This model can also be used as a fading channel simulator. A Markov model describing the transition between non-fade and fade states is combined with a Rician model for the multipath fading. This model produces propagation data which very closely match the statistical characteristics. such as fade duration, non-fade duration and fade depth, obtained from measured data. Cumulative distributions of fade duration and non-fade duration obtained from Markov sequences are shown. Propagation data measured in Melbourne, Australia, by using Japan's ETS-V satellite are used.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
