The performance of a hybrid satellite-terrestrial relay system using non-orthogonal multiple access (HSTRS-NOMA) is studied in this paper. In the satellite communication scenario considered in this paper, a satellite transmits signals to a terrestrial user under the help of a terrestrial decode-and-forward relay. We derive the achievable average rate and the outage probability of the system under independent Shadowed-Rician satellite channels and Nakagami fading terrestrial channels. Furthermore, the asymptotic outage probability of the system in the case of high signal-to-noise ratio (SNR) is proposed. Finally, we present the simulation results to verify the theoretical results.
