Performance and Phase Optimization of Energy-Harvesting Enabled Multi-User RIS-Assisted Cooperative NOMA Systems Over κ–μ Shadowed Fading

Reconfigurable intelligent surfaces (RISs) and non-orthogonal multiple access (NOMA) are often analyzed under idealized assumptions such as fully active RIS panels, perfect phase control, and cooperative relaying models that neglect RIS control energy. These assumptions can overestimate reliability in hardware-constrai...
