Treffer: Successful Transmission Probability Analysis of the Satellite-Maritime Uplink: A Stochastic Geometry Based Approach.

Harmonized satellite-maritime networks hold the promise of seamlessly filling the maritime coverage-holes, hence they have attracted substantial research interests. In this broad context, we study the scenario of remote geographic locations, where the satellite supports multiple users on the sea. However, given the limited handset-power, the direct user-satellite uplink (UL) tends to be weak in realistic fading environments. Hence, we enhance the link by relaying and investigate the relay-assisted terrestrial-maritime UL, where the power-domain non-orthogonal multiple access (NOMA) scheme is conceived for the efficient exploitation of the limited frequency resources. The associated pros and cons are then quantified in the face of the resultant interference by relying on the powerful analysis technique of stochastic geometry, where the location of users is modeled by a homogeneous Poisson point process (HPPP). The successful transmission probability of users at both the ship-based base station (BS) and the satellite is derived. Simulation results verified the accuracy of our analysis. Moreover, the superiority of the proposed NOMA-based scheme over random access is demonstrated. [ABSTRACT FROM AUTHOR]
