Pointing-and-Acquisition for Optical Wireless in 6G: From Algorithms to Performance Evaluation
The increasing demand for wireless communication services has led to the development of non-terrestrial networks, which enables various air and space applications.
Sparse RF Lens Antenna Array Design for AoA Estimation in Wideband Systems: Placement Optimization and Performance Analysis
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 advanced 5G vehicle-to-everything (V2X) use cases that demand wider bandwidths and higher data rates.
AoA-based Position and Orientation Estimation Using Lens MIMO in Cooperative Vehicle-to-Vehicle Systems
Positioning accuracy is a critical requirement for vehicle-to-everything (V2X) use cases.
On the Role of ViT and CNN in Semantic Communications: Analysis and Prototype Validation
Semantic communications have shown promising advancements by optimizing source and channel coding jointly.
Measurement-based Close-in Path Loss Modeling with Diffraction for Rural Long-distance Communications
This research demonstrates that the newly developed CI path loss models incorporating a diffraction component significantly reduce standard deviations (STD) and are independent of frequency, especially for LOS beyond the first meter of propagation, making them suitable for use with frequencies up to a millimeter-wave.
Free-Space Optical Communications for 6G Wireless Networks: Challenges, Opportunities, and Prototype Validation
In this study, we perform video signal transmissions via an FPGA-based FSO communication prototype to investigate the feasibility of an FSO link with a distance of up to 20~km.
Dynamic RF Beam Codebook Reduction for Cost-Efficient mmWave Full-Duplex Systems
The recent attempts to realize full-duplex (FD) communications in millimeter wave (mmWave) systems have garnered a significant amount of interest for its potential.
Beyond Transmitting Bits: Context, Semantics, and Task-Oriented Communications
Communication systems to date primarily aim at reliably communicating bit sequences.
Analog Self-Interference Cancellation with Practical RF Components for Full-Duplex Radios
In this paper, we derive a closed-form expression for the SIC performance of the multi-tap circuit; we consider how the RF components must overcome such practical impairments as digitally-controlled attenuators, phase shifters, and PA. For a realistic performance analysis, we exploit the measured PA characteristics and carry out a 3D ray-tracing-based, system-level throughput analysis.
Demo: Real-Time Semantic Communications with a Vision Transformer
Semantic communications are expected to enable the more effective delivery of meaning rather than a precise transfer of symbols.
Beam Squint in Ultra-wideband mmWave Systems: RF Lens Array vs. Phase-Shifter-Based Array
In terms of the beam squint, we compare the proposed RF lens antenna with the phase shifter-based array for hybrid beamforming.
RF Lens Antenna Array-Based One-Shot Coarse Pointing for Hybrid RF/FSO Communications
Because of its high directivity, free-space optical (FSO) communication offers a number of advantages.
