Optimal Interference Exploitation Waveform Design with Relaxed Block-Level Power Constraints
Xiao Tong, Lei Lei, Ang Li +2
This paper investigates constructive interference (CI)-based waveform design for phase shift keying and quadrature amplitude modulation symbols under relaxed block-level power cons…
AI-Driven Optimization of Wave-Controlled Reconfigurable Intelligent Surfaces
Gal Ben Itzhak, Miguel Saavedra-Melo, Ender Ayanoglu +2
A promising type of Reconfigurable Intelligent Surface (RIS) employs tunable control of its varactors using biasing transmission lines below the RIS reflecting elements. Biasing st…
