Channel2World: A Wireless Foundation Model for RF Environment Representation
Hyung-Joo Moon, Joonkyu Jang, Kwang Soon Kim +3
Wireless channels are commonly treated as link-specific observations, although their multipath structure is governed by the surrounding radio-frequency (RF) environment. In this pa…
Physically Consistent Channel Modeling and Signal Processing for Reconfigurable Wireless Systems
Ahmad Dkhan, Simon Tarboush, Hadi Sarieddeen +3
Reconfigurable antennas are increasingly integrated into multi-antenna communication systems to exploit large apertures while reducing the hardware complexity, energy consumption,…
Energy Efficiency Optimization in Distributed MIMO vRAN via Cross-Layer Link Abstraction
Jaebum Park, Chan-Byoung Chae, Robert W. Heath
Virtualized radio access networks (vRAN) run the compute-intensive multiple-input multiple-output (MIMO) baseband as software on shared servers, which makes energy efficiency (EE)…
Symbol Distributions in Semantic Communications: A Source-Channel Equilibrium Perspective
Hanju Yoo, Dongha Choi, Songkuk Kim +2
Semantic communication systems often use end-to-end neural networks to map input data into continuous symbols. These symbols, which are essentially neural network features, have fi…
Bridging Neural Networks and Wireless Systems with MIMO-OFDM Semantic Communications
Hanju Yoo, Dongha Choi, Yonghwi Kim +4
Semantic communications aim to enhance transmission efficiency by jointly optimizing source coding, channel coding, and modulation. While prior research has demonstrated promising…
Accelerating vRAN and O-RAN with SIMD: Architectural Perspectives and Performance Evaluation
Jaebum Park, Chan-Byoung Chae, Robert W. Heath
The evolution of radio access networks (RANs) toward virtualization and openness creates new opportunities for flexible, cost-effective, and high-performance deployments. Achieving…
