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…
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…
On the Role of ViT and CNN in Semantic Communications: Analysis and Prototype Validation
Hanju Yoo, Linglong Dai, Songkuk Kim +1
Semantic communications have shown promising advancements by optimizing source and channel coding jointly. However, the dynamics of these systems remain understudied, limiting rese…
Measurement-based Close-in Path Loss Modeling with Diffraction for Rural Long-distance Communications
Jaedon Park, Hong-Bae Jeon, Jungho Cho +1
In this letter, we investigate rural large-scale path loss models based on the measurements in a central area of South Korea (rural area) in spring. In particular, we develop new c…
On Propagation Characteristics of Reconfigurable Surface Wave Platform: Simulation and Experimental Verification
Z. Chu, K. F. Tong, K. K. Wong +2
Reconfigurable intelligent surface (RIS) as a smart reflector is revolutionizing research for next-generation wireless communications. Complementing this is a concept of using RIS…
