Performance Analysis of Satellite Communication Systems With Randomly Located Ground Users

Abstract

Satellite communication (SatCom) is one of the emerging technologies that overcome digital divide between urban and remote areas. The outage event of SatCom link connecting to a network is more critical in an infrastructuredeficient remote area. In this paper, we analyze outage probability (OP) and symbol error rate (SER) over SatCom downlink channels when the users are randomly located in single beam and multibeam area. The downlink beams will suffer from propagation loss and the shadowed-Rician fading depending on the user location which is assumed to follow a Poisson point process. For mathematically tractable, informative, and insightful interpretation, we obtain the asymptotic OP and SER expressions of user link under several channel conditions in the high power regime. Finally, numerical results are presented to verify the analysis and show the accuracy of the asymptotic results.
