A Heuristic-Integrated DRL Approach for Phase Optimization in Large-Scale RISs
Wei Wang, Peizheng Li, Angela Doufexi +1
Optimizing discrete phase shifts in large-scale reconfigurable intelligent surfaces (RISs) is challenging due to their non-convex and non-linear nature. In this letter, we propose…
