Analysis of Maritime Mobile Satellite Communication Systems

Abstract

The communication channel between a satellite and a ship earth station (SES) is described by a model which includes multipath fading, doppler shift and noise. Multipath fading is caused by reflections from the sea surface. These reflections can affect the system performance, especially at low elevation angles or when SES is using low gain antennas. Doppler shift is a very important effect when using low altitude satellites, because of the high velocities involved. This thesis describes and presents a software simulator for multipath fading in the maritime communications environment. Analysis of throughput of an unslotted Aloha maritime mobile satellite communication channel is also presented. Keywords: Theses.
