Analog RF Computing for Integrated Data and AI Flows Over Wireless Networks
Wentao Yu, Vincent W. S. Wong
Many resource-constrained edge devices require artificial intelligence (AI) services but are not powerful enough to store or execute neural networks (NNs). Analog radio frequency (…
Analog RF Computing: A New Paradigm for Energy-Efficient Edge AI Over MU-MIMO Systems
Wentao Yu, Vincent W. S. Wong
Modern edge devices increasingly rely on neural networks for intelligent applications. However, conventional digital computing-based edge inference requires substantial memory and…
Agentic AI for Intent-driven Optimization in Cell-free O-RAN
Mohammad Hossein Shokouhi, Vincent W. S. Wong
Agentic artificial intelligence (AI) is emerging as a key enabler for autonomous radio access networks (RANs), where multiple large language model (LLM)-based agents reason and col…
Cooperative ISAC for Joint Localization and Velocity Estimation in Cell-Free MIMO Systems
Zihuan Wang, Vincent W. S. Wong, Robert Schober
In this paper, we explore a cooperative integrated sensing and communication (ISAC) framework that utilizes orthogonal frequency division multiplexing (OFDM) waveforms. Under the c…
Heterogeneous Graph Neural Network for Cooperative ISAC Beamforming in Cell-Free MIMO Systems
Zihuan Wang, Vincent W. S. Wong
Integrated sensing and communication (ISAC) is one of the usage scenarios for the sixth generation (6G) wireless networks. In this paper, we study cooperative ISAC in cell-free mul…
