Velocity Index Modulation for Movable Antenna Systems
Yan Zhang, Indrakshi Dey, Shuaishuai Han +2
In movable antenna (MA) systems, antenna movement induces Doppler frequency shifts that are conventionally treated as an impairment requiring mitigation. In this paper, we propose…
A Family of Hybrid Beyond-Diagonal RIS Architectures: Design and Performance Analysis
Konstantinos Ntougias, Ioannis Krikidis
Beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) extend conventional diagonal RISs by allowing inter-element coupling, thereby enlarging the set of attainable scatteri…
Secure and Robust Beamforming Design for STAR-RIS-aided MU-MIMO ISAC Systems
Rakesh Ranjan, Anshu Mukherjee, Manjesh K. Hanawal +2
Simultaneous transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS) offer a transformative approach for integrated sensing and communication (ISAC) systems, par…
Improving Reliability of Hybrid Bit-Semantic Communications for Cellular Networks
Nikos G. Evgenidis, Sotiris A. Tegos, Panagiotis D. Diamantoulakis +2
Semantic communications (SemComs) have been considered as a promising solution to reduce the amount of transmitted information, thus paving the way for more energy-and spectrum-eff…
Asymmetric Modulation Design for Fluid-Antenna SWIPT Systems
Ahsan Mehmood, Ioannis Krikidis, Ghassan M. Kraidy
In this work, we propose the design of modulation schemes that improve the rate-energy region of fluid antenna-assisted simultaneous wireless information and power transfer (SWIPT)…
Dependability Theory-based Statistical QoS Provisioning of Fluid Antenna Systems
Irfan Muhammad, Priyadarshi Mukherjee, Wee Kiat New +3
Fluid antenna systems (FAS) have recently emerged as a promising technology for next-generation wireless networks, offering real-time spatial reconfiguration to enhance reliability…
