Outage analysis for full-duplex relaying satellite-terrestrial NOMA systems

Abstract

In this paper, the outage performance for a full-duplex (FD) relaying satellite-terrestrial system is investigated. The system consists of a satellite source, a relay, and two users. Firstly, the satellite transmits the information of two users to the FD relay, and then the relay decodes and forwards the information to both users. Herein, the non-orthogonal multiple access protocol is used to incorporate the signal of two users. We investigate the system outage performance in the presence of residual self-interference of the relay and derive the exact expressions of outage probability for two users. Moreover, the accuracy of the results is verified with Monte-Carlo simulations.
