Ambiguity-Resolved Micro-Doppler Construction for Asynchronous Bistatic Sensing
Yiyi Xu, Zhongqin Wang, Kai Wu +1
Integrated sensing and communications (ISAC) can turn wireless networks into pervasive sensing platforms, but bistatic deployments are impaired by transceiver clock asynchrony, whi…
WiFi Sensing via Reservoir Computing
Heping Wang, Zhongqin Wang, J. Andrew Zhang
Practical WiFi sensing must handle clock-asynchronous links, cross-domain variation, and post-deployment updating under the limited compute budget of access point (AP), router, and…
Posterior-Aware Differential Channel Tracking for Reliable Single-Stream DAB+ Passive Radar
Kai Wu, Brendan Hall, Zhongqin Wang +2
Digital audio broadcasting plus (DAB+) is an attractive illuminator for passive radar because it provides persistent, high-power, and geographically widespread very high frequency…
Rethinking RSSI for WiFi Sensing
Zhongqin Wang, J. Andrew Zhang, Kai Wu +1
The Received Signal Strength Indicator (RSSI) is ubiquitously available on commodity WiFi devices but is commonly regarded as too coarse for fine-grained sensing. This paper revisi…
ISAC: From Human to Environmental Sensing
Kai Wu, Zhongqin Wang, Shu-Lin Chen +2
Integrated Sensing and Communications (ISAC) is poised to become one of the defining capabilities of the sixth generation (6G) wireless communications systems, enabling the network…
Water Level Sensing via Communication Signals in a Bi-Static System
Zhongqin Wang, J. Andrew Zhang, Kai Wu +1
Accurate water level sensing is essential for flood monitoring, agricultural irrigation, and water resource optimization. Traditional methods require dedicated sensor deployments,…
