Abstract

Empowered by integrated sensing and communications (ISAC), 6G Perceptive Mobile Network is expected to offer ubiquitous sensing capability, leveraging the communications infrastructure. Bi-static sensing can bypass the stringent full-duplex requirement in mono-static sensing and is more practical for (near-term) implementation. It also offers great spatial sensing diversity. Clock asynchronism, which naturally exists between spatially separated communication nodes, is a central and challenging problem in bi-static sensing. It can cause ranging ambiguity and prevent coherent processing of dis-continuous measurements (e.g., for Doppler frequency estimation). Should it be resolved, sensing can be efficiently realized in communication networks, requiring almost no network infrastructure and hardware changes. 

This talk delves into advanced techniques for addressing the clock asynchronism challenge in the integration, focusing on efficient solutions requiring only a single receiver. We first introduce this issue in the context of 6G perceptive mobile networks. Following this, we provide a comprehensive review of the latest single-receiver-based solutions, applicable to both multi-antenna and single-antenna configurations. Additionally, we showcase our cutting-edge sensing applications developed using these techniques, including moving object tracking, localization, and environmental sensing such as rainfall and water level detection. The talk concludes by highlighting unresolved challenges and exploring future research directions in this evolving field.

Biography

Dr J. Andrew Zhang (M'04-SM'11) is a Professor in the School of Electrical and Data Engineering, University of Technology Sydney, Australia. His research interests are in the area of signal processing for wireless communications and sensing. Prof. Zhang has published more than 300 papers in leading Journals and conference proceedings, and has won 5 best paper awards. He is a recipient of CSIRO Chairman's Medal and the Australian Engineering Innovation Award in 2012 for exceptional research achievements in multi-gigabit wireless communications.

Prof. Zhang is one of the pioneer researchers in integrated sensing and communications (ISAC). He initiated the concept of perceptive mobile network, by defining its system framework and demonstrating its feasibility in a set of papers back in 2017. He has published a monograph, three book chapters, and more than 60 journal papers in this area. Prof. Zhang co-organized multiple ISAC workshops at leading conferences and special issues in leading IEEE journals. He has delivered ISAC tutorials in multiple conferences, such as WCNC 2021, ICC 2021, ICC 2022, IEEE Radar 2023, and numerous keynotes and invited talks. He is serving as an elected member of the IEEE Signal Processing Society ISAC Working Group, the publication co-chair of the IEEE Communication Society's ISAC Emerging Technology Initiative (ISAC-ETI), and the Editor-in-Chief for its official publication, the ISAC-Focus. Prof. Zhang has received more than six million dollars of research funds in this area. For details, please refer to https://sites.google.com/view/andrewzhang/.
