Dear Colleagues and Students,

The State Key Laboratory of Internet of Things for Smart City would like to invite you to join our “IOTSC Talk Series” on 1/12/2025 (Monday). We are pleased to invite Prof. J. Andrew Zhang from University of Technology Sydney, Australia as the speaker.

Bi-Static Sensing for Next Generation Perceptive Communication Networks: Technologies and Applications
Speaker: Prof. J. Andrew Zhang
Date: 1/12/2025 (Monday)
Time: 10:30 – 11:30
Language: English
Venue: N21-6007

Abstract:
Integrated Sensing and Communications (ISAC) represents a paradigm shift from conventional communication-only networks toward systems that natively integrate radar-like sensing capabilities. It has become a foundational technology for next-generation wireless systems, including Wi-Fi and 6G networks.
Bi-static sensing, where a sensing receiver exploits signals transmitted by another node, naturally aligns with the topology of communication networks. It circumvents the stringent full-duplex requirements of mono-static sensing and offers enhanced spatial sensing diversity. However, clock (Local oscillating signal) asynchronism, which inherently exists among spatially separated communication nodes, poses a central and challenging problem. It can cause ranging ambiguities and disrupt coherent processing of discontinuous measurements, such as those required for Doppler frequency estimation. If effectively resolved, sensing could be seamlessly realized within existing communication infrastructures, requiring minimal hardware or architectural modifications.
This talk explores advanced techniques for tackling clock asynchronism in bi-static sensing, with a focus on efficient single-receiver-based solutions. The problem will first be introduced in the context of 6G perceptive mobile networks, followed by a comprehensive overview of recent methods applicable to both multi-antenna and single-antenna configurations. I will then present our latest sensing applications developed using these techniques, including moving-object tracking, respiration and heartbeat monitoring, behavior recognition, and environmental sensing such as rainfall and water-level detection. The talk concludes by outlining key open challenges and future research directions in this rapidly evolving field.
