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…
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…
AI-Enhanced Wide-Area Data Imaging via Massive Non-Orthogonal Direct Device-to-HAPS Transmission
Hyung-Joo Moon, Chan-Byoung Chae, Kai-Kit Wong +1
Massive Aerial Processing for X MAP-X is an innovative framework for reconstructing spatially correlated ground data, such as environmental or industrial measurements distributed a…
The Tri-Hybrid MIMO Architecture
Robert W. Heath, Joseph Carlson, Nitish Vikas Deshpande +3
We present an evolution of multiple-input multiple-output (MIMO) wireless communications known as the tri-hybrid MIMO architecture. In this framework, the traditional operations of…
Beamforming with hybrid reconfigurable parasitic antenna arrays
Nitish Vikas Deshpande, Miguel Rodrigo Castellanos, Saeed R. Khosravirad +3
A parasitic reconfigurable antenna array is a low-power approach for beamforming using passive tunable elements. Prior work on reconfigurable antennas in communication theory is ba…
Embracing Reconfigurable Antennas in the Tri-hybrid MIMO Architecture for 6G and Beyond
Miguel Rodrigo Castellanos, Siyun Yang, Chan-Byoung Chae +1
Multiple-input multiple-output (MIMO) communication has led to immense enhancements in data rates and efficient spectrum management. The evolution of MIMO, though, has been accompa…
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…
