STAR-RIS Assisted Full-Duplex Communication Networks
Abdelhamid Salem, Kai-Kit Wong, Chan-Byoung Chae +1
Different from conventional reconfigurable intelligent surfaces (RIS), a recent innovation called simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-…
Pointing-and-Acquisition for Optical Wireless in 6G: From Algorithms to Performance Evaluation
Hyung-Joo Moon, Chan-Byoung Chae, Kai-Kit Wong +1
The increasing demand for wireless communication services has led to the development of non-terrestrial networks, which enables various air and space applications. Free-space optic…
Fluid Antenna-Assisted Dirty Multiple Access Channels over Composite Fading
Farshad Rostami Ghadi, Kai-Kit Wong, F. Javier Lopez-Martinez +3
This letter investigates the application of the emerging fluid antenna (FA) technology in multiuser communication systems when side information (SI) is available at the transmitter…
Active RIS-Assisted MIMO-OFDM System: Analyses and Prototype Measurements
De-Ming Chian, Feng-Ji Chen, Yu-Chen Chang +5
In this study, we develop an active reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) prototyp…
Sparse RF Lens Antenna Array Design for AoA Estimation in Wideband Systems: Placement Optimization and Performance Analysis
Joo-Hyun Jo, Jae-Nam Shim, Chan-Byoung Chae +2
In this paper, we propose a novel architecture for a lens antenna array (LAA) designed to work with a small number of antennas and enable angle-of-arrival (AoA) estimation for adva…
AoA-based Position and Orientation Estimation Using Lens MIMO in Cooperative Vehicle-to-Vehicle Systems
Joo-Hyun Jo, Jae-Nam Shim, Byoungnam +3
Positioning accuracy is a critical requirement for vehicle-to-everything (V2X) use cases. Therefore, this paper derives the theoretical limits of estimation for the position and or…
