Shuffling for Semantic Secrecy
Fupei Chen, Liyao Xiang, Haoxiang Sun +2
Deep learning draws heavily on the latest progress in semantic communications. The present paper aims to examine the security aspect of this cutting-edge technique from a novel shu…
Enhancing Communications and Sensing Simultaneously by Zero-Order Optimization of MTS
Wenhai Lai, Kaiming Shen
Metasurface (MTS) comprises an array of meta-atoms, each reflecting and inducing a phase shift into the incident wireless signal. We seek the optimal combination of phase shifts ac…
FollowSpot: Enhancing Wireless Communications via Movable Ceiling-Mounted Metasurfaces
Wenhai Lai, Kaiming Shen, Rui Zhang
This paper studies the optimal placement of ceiling-mounted metasurfaces (MTSs) to help focus the wireless signal beam onto the target receiver, as inspired by the theatre spotligh…
Blind Passive Beamforming for MIMO System
Wenhai Lai, Jiawei Yao, Kaiming Shen
Passive beamforming for the intelligent surface (IS)-aided multiple-input multiple-output (MIMO) communication is a difficult nonconvex problem. It becomes even more challenging un…
Intelligent Surface Assisted Radar Stealth Against Unauthorized ISAC
Fan Xu, Wenhai Lai, Kaiming Shen
The integration of radar sensors and communication networks as envisioned for the 6G wireless networks poses significant security risks, e.g., the user position information can be…
A Semantic Approach to Successive Interference Cancellation for Multiple Access Networks
Mingxiao Li, Kaiming Shen, Shuguang Cui
Differing from the conventional communication system paradigm that models information source as a sequence of (i.i.d. or stationary) random variables, the semantic approach aims at…
