Electromagnetic Twin: Completing the Wireless World from Sparse Channel Evidence
Tuo Wu, Jie Tang, Kangda Zhi +5
Acquiring dense channel information over many locations and beams incurs considerable pilot and processing overhead. Radio maps and channel knowledge maps (CKMs) reduce this overhe…
Fronthaul-Efficient Distributed Cooperative 3D Positioning with Quantized Latent CSI Embeddings
Tong An, Jiwei Zhao, Jiayang Shi +5
The paper proposes a learning‑based edge‑cloud framework that compresses channel state information (CSI) at distributed base stations into quantized latent embeddings for fronthaul…
ConsisFormer: Compute-Efficient Transformer for Wireless Foundation Models Based on Channel Consistency
Yuwei Wang, Li Sun, Tingting Yang +4
Wireless foundation models (WFMs) have recently emerged as a promising paradigm for AI-native 6G networks, enabling universal channel representations adaptable to diverse communica…
Beyond the RF Paradigm: Rydberg Atomic Receivers for Next-Generation IoT
Qihao Peng, Qu Luo, Dongnan Xia +11
Next-generation Internet-of-Things (IoT) is evolving toward a ubiquitous, ultra-low-power, and multi-band heterogeneous networking paradigm that seamlessly integrates terrestrial,…
Scalable Fluid Antenna Systems: A New Paradigm for Array Signal Processing
Tuo Wu, Ye Tian, Jie Tang +8
Most existing antenna array-based source localization methods rely on fixed-position arrays (FPAs) and strict assumptions about source field conditions (near-field or far-field), w…
How Many Independent Modes Does a Fluid Antenna Have? A Closed-Form Outage Analysis via Equivalent Degrees of Freedom
Tuo Wu, Junteng Yao, Kai-Kit Wong +5
In a fluid antenna system (FAS), a single reconfigurable antenna is able to activate one of correlated ports to exploit spatial diversity. However, outage analysis is challengi…
