Secure Downlink Transmission with NOMA-Based Mixed FSO/RF Communications in Space–Air–Ground Integrated Networks

Security is paramount in space–air–ground integrated networks (SAGINs) due to their inherent openness and the broadcast characteristics of wireless transmission. In this paper, we propose a secure downlink transmission scheme with NOMA-based mixed FSO/RF communications for SAGINs. Specifically, the...
