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…
Real-Time Burst-Mode Digital Signal Processing for Passive Optical Networks
Ji Zhou, Kainan Wu, Haide Wang +6
Driven by the ever-increasing capacity demands, the 50G passive optical network (PON) is maturing gradually. One of the main challenges for the 50G PON is implementing burst-mode d…
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…
