Secrecy Rate Optimization for Secure and Green Communication Systems Enabled by Cooperative Aerial Active RIS and STAR-RIS
Aerial reconfigurable intelligent surfaces (ARISs), which integrate uncrewed aerial vehicles (UAVs) with RISs, have become a potential paradigm for secure wireless transmission. However, a single ARIS suffers from the inherent multiplicative fading effect and limited spatial beamforming flexibility, thereby significant...
