Abstract: Due to the limited coverage of reflecting-only reconfigurable intelligent surfaces (RIS), the existing RIS-assisted physical-layer key generation (PKG) scheme limits its overall performance ...
Abstract: The incredible potentiality of reconfigurable intelligent surface (RIS) in addressing power supply and obstacle environment of Internet of Medical Things (IoMT) has been capturing our ...
Abstract: Stacked intelligent metasurface (SIM) is an emerging design that consists of multiple layers of metasurfaces. A SIM enables holographic multiple-input multiple-output (HMIMO) precoding in ...
Abstract: In this paper, we study a novel joint information-theoretic secrecy and covertness model for an unmanned aerial vehicle (UAV)-assisted finite blocklength transmission system, in which an UAV ...
Abstract: Unlike conventional fixed-antenna architectures, rotatable antenna (RA) has shown great potential in enhancing wireless communication performance by exploiting additional spatial degrees of ...
Abstract: This paper focuses on maximizing the sum secrecy rate in secure multi-user MISO communication systems that use stacked intelligent metasurfaces (SIM). SIM technology manipulates ...
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: 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 ...
Jon Anderson and the Band Geeks have added more dates to their 2026 tour. The former Yes singer and his current group previously announced 10 U.S. dates beginning in April and running through early ...
