“…For modeling satellite channels, the shadowed-Rician fading model was proposed in [8], which has been proved its suitability in various frequency bands, e.g., the UHF-band, L-band, Sband, and Ka-band. A simpler model for the shadowed-Rician fading by using the Nakagami distribution for the amplitude of line-of-sight (LOS) component was proposed in [9] and is widely adopted to analyze the system performance of satellite communication systems [10]- [12]. The outage probability of Noise spectral density a shared-band on-board processing satellite communication system was analyzed under the shadowed-Rician fading where the satellite has digital processing capability in [10].…”

For small-scale fading, the shadowed-Rician fading is assumed, which is widely adopted for satellite channels [10]- [12].

In this paper, we consider a downlink satellite communication system where multiple satellites are uniformly distributed over a sphere at a certain altitude. We analytically derive three things: 1) the satellite-visible probability for a given location, which is defined as the probability that a terminal sees at least one satellite above the minimum elevation angle, i.e., a predefined elevation angle above which the terminal can be served by a satellite, 2) the distribution of distance between the terminal and serving satellite when the terminal is associated with the nearest satellite, and 3) the exact expressions for the outage probability and throughput of the system. With the derived expressions, the system throughput maximization problem is formulated under the satellite-visibility and outage constraints. To solve the problem, we reformulate the problem with bounded feasible sets and obtain the optimal solution by using an exhaustive search. Using the Poisson limit theorem, we derive approximated expressions for the satellite-visible probability, outage probability, and system throughput, which reduce computational complexity of performance evaluation and search time for the optimal solution of the throughput maximization problem. Simulation results perfectly match the derived exact expressions for the outage probability and system throughput. It is also shown that the analytical results of the approximated expressions are fairly close to those of the exact expressions.
