Abstract: Extremely large-scale multiple-input multiple-output (XL-MIMO) communications and ultra-high frequency bands are both potential enablers for satisfying extreme performance requirements of ...
Abstract: In this paper, we propose a robust secrecy transmission scheme for intelligent reflecting surface (IRS) aided communication systems. Different from all the existing works where IRS has ...
Abstract: Modular extremely large-scale array (mXL-array) represents a novel architecture for the extremely large aperture array (ELAA), offering extended coverage and significantly enhanced spatial ...
Abstract: This work considers a dual-functional radar and communication (DFRC) system with an active reconfigurable intelligent surface (RIS) and a potential eavesdropper. Our purpose is to maximize ...
