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…
Wireless Communications in Doubly Selective Channels with Domain Adaptivity
J. Andrew Zhang, Hongyang Zhang, Kai Wu +3
Wireless communications are significantly impacted by the propagation environment, particularly in doubly selective channels with variations in both time and frequency domains. Ort…
Sensing in Bi-Static ISAC Systems with Clock Asynchronism: A Signal Processing Perspective
Kai Wu, Jacopo Pegoraro, Francesca Meneghello +9
Integrated Sensing and Communication (ISAC) has been identified as a pillar usage scenario for the impending 6G era. Bi-static sensing, a major type of sensing in ISAC, is promisin…
