Channel Gains to Captions: Task-Unified Multi-Level RF Sensing with Vision-Language Models
Tianyu Hu, Zhiren Gong, Haowei Cui +6
This letter investigates a task-unified multi-level radio-frequency (RF) sensing framework driven by vision-language models (VLMs). Existing RF sensing methods rely on task-specifi…
Single-Model Adaptive Wireless Image Transmission via Feature Sparsity Regularization
Xianghao Cui, Li Lan, Qi He +4
Learned joint source-channel coding (JSCC) enables robust wireless image transmission by jointly optimizing the transmitter and receiver over differentiable channel models. For ban…
Bending Beam for THz Wireless Networks: Fundamental, Design Issue, and Prototype
Aoran Liu, Xin Tong Hu, Weidong Mei +5
Bending beams, characterized by their non diffracting and self-healing properties in the near field, offer a new approach to bypass blockage in terahertz (THz) wireless communicati…
Advancing THz Radio Map Construction and Obstacle Sensing: An Integrated Generative Framework in ISAC
Tianyu Hu, Shuai Wang, Yunhang Xie +7
Integrated sensing and communication (ISAC) in the terahertz (THz) band enables obstacle detection, which in turn facilitates efficient beam management to mitigate THz signal block…
Towards THz-based Obstacle Sensing: A Generative Radio Environment Awareness Framework
Tianyu Hu, Yunhang Xie, Shuai Wang +3
Obstacle sensing is essential for terahertz (THz) communication since the subsequent beam management can avoid THz signals blocked by the obstacles. In parallel, radio environment,…
