RadPose: ISAC-based RF 3D Human Pose Estimation
Geo Jie Zhou, Kunzhe Song, Ruxin Lin +1
Human pose estimation under adverse lighting and occlusion conditions remains challenging for camera- and LiDAR-based systems. Although mmWave radars provide robustness to illumina…
Self-Supervised Doppler-Guided RF Odometry
Kunzhe Song, Jialuo Du, Jingkai Lin +1
Radio-frequency (RF) sensing enables robot ego-motion estimation in darkness, smoke, and fog, yet RF odometry remains challenging because multipath and moving reflectors make cross…
Rascene: High-Fidelity 3D Scene Imaging with mmWave Communication Signals
Kunzhe Song, Geo Jie Zhou, Xiaoming Liu +1
Robust 3D environmental perception is critical for applications such as autonomous driving and robot navigation. However, optical sensors such as cameras and LiDAR often fail under…
OFDM Waveform for Monostatic ISAC in 6G: Vision, Approach, and Research Directions
Huacheng Zeng, Kunzhe Song, Geo Jie Zhou +1
Integrated sensing and communication (ISAC) is widely regarded as a key enabling technology for 6G wireless networks. While extensive research has explored the coexistence of sensi…
Spectrum Shortage for Radio Sensing? Leveraging Ambient 5G Signals for Human Activity Detection
Kunzhe Song, Maxime Zingraff, Huacheng Zeng
Radio sensing in the sub-10 GHz spectrum offers unique advantages over traditional vision-based systems, including the ability to see through occlusions and preserve user privacy.…
ChatTracer: Large Language Model Powered Real-time Bluetooth Device Tracking System
Qijun Wang, Shichen Zhang, Kunzhe Song +1
Large language models (LLMs) have transformed the way we interact with cyber technologies. In this paper, we study the possibility of connecting LLM with wireless sensor networks (…
