Abstract

Abstract

The system Ergodic Sum Rate (ESR) performance of a mixed Free Space Optical/ Radio Frequency (FSO/RF) Satellite-Aerial-Terrestrial Integrated Network (SATIN) combining multi-antenna beamforming scheme and uplink Non-Orthogonal Multiple Access (NOMA) technology is investigated in this paper. Firstly, a beamforming scheme using statistical channel state information is proposed to maximize the ESR of the considered system, where multi-antenna UAV is deployed with uplink NOMA technology. Secondly, under the assumption that the satellite-UAV link with FSO undergoes Gamma-Gamma fading while the UAV-terrestrial links adopted RF experience correlated Rayleigh fading, the closed-form expression for ESR of the considered SATIN is derived. Finally, numerical results are provided to validate the theoretical analysis. The simulation results show that, compared with the Orthogonal Multiple Access (OMA) scheme, the proposed scheme improves the system ESR, and the proposed scheme has the performance superiority over the other benchmark beamforming scheme.
