Secure Satellite Downlink With Hybrid RIS and AI-Based Optimization

Secure Satellite Downlink With Hybrid RIS and AI-Based Optimization

In this paper, we explore a secure multiuser multiple-input single-output (MISO) satellite downlink communication system, enhanced by the integration of a hybrid reconfigurable intelligent surface (RIS). The study formulates a robust joint design for satellite and RIS beamforming, aimed at maximizin...
