Cyclic-Prefix OFDM Probing for Spatial-ISI-Free Distributed Acoustic Sensing via Frequency-Domain Channel Reconstruction
Huan Huang, Zhiyang Xue, Ziang Chen +4
Matched-filter-based pulse-compression distributed acoustic sensing (DAS) suffers from nonzero compression sidelobes that cause deterministic inter-range-bin leakage, i.e., spatial…
Unsupervised Semi-Parametric Plug-in Likelihood-Ratio Detection for Covert Communications in the Presence of Disco Reconfigurable Intelligent Surfaces
Luyao Sun, Huan Huang, Yongxing Song +5
Covert communications, also referred to as low probability of detection (LPD) communications, provide a higher level of privacy protection than cryptography and physical-layer secu…
Simultaneously Exposing and Jamming Covert Communications via Disco Reconfigurable Intelligent Surfaces
Huan Huang, Hongliang Zhang, Yi Cai +3
Covert communications provide a stronger privacy protection than cryptography and physical-layer security (PLS). However, previous works on covert communications have implicitly as…
Disco Intelligent Omni-Surfaces: 360-degree Fully-Passive Jamming Attacks
Huan Huang, Hongliang Zhang, Jide Yuan +6
Intelligent omni-surfaces (IOSs) with 360-degree electromagnetic radiation significantly improves the performance of wireless systems, while an adversarial IOS also poses a signifi…
