Performance Analysis of Satellite Communication Systems with Randomly Located Ground Users

Abstract

Satellite communication (SatCom) is one of the emerging technologies that compensate for digital divide between urban and remote areas. The outage event of SatCom link connecting to a network is more critical in an infrastructure deficient remote area. In this paper, we analyze an outage probability (OP) and symbol error rate (SER) over SatCom downlink channels when the users are randomly located in a single beam area. The downlink beam 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 and verify the asymptotic OP and SER expressions of user link under several channel conditions in the high power regime.
