Coverage Analysis of Cooperative Satellite-UAV-Terrestrial Communication System with Receiver Mobility

UAVs are recently considered as propitious solution for development of long-distance communication due to their large line-of-sight transmission compared to terrestrial relays. In this paper, we examine a UAV assisted satellite terrestrial communication system which consists of satellite (S), mobile terrestrial receivers (D) and a stationary UAV (R). Specifically, considering the relative velocity and the random position of receivers, we analyse the R-D link for evaluation of the instantaneous SNR considering the error estimation of channel gain and noise, using first order auto-regressive process. Moreover, the expression for coverage probability is derived and analysed. Finally the derived numerical results are verified using Monte Carlo simulations.
