Event-Adaptive Motion Planning with Distilled Vision-Language Model in Safety-Critical Situations
Zhenwei Huang, Changsheng You, Shuai Wang +3
Robot navigation in safety-critical scenarios faces significant challenges from unforeseen semantic events, where collisions arise primarily from the unpredictable behaviors of dyn…
Mixed Near-field and Far-field Localization in Extremely Large-scale MIMO Systems
Cong Zhou, Changsheng You, Chao Zhou +2
In this paper, we study efficient \emph{mixed near-field and far-field} target localization methods in extremely large-scale multiple-input multiple-output (XL-MIMO) systems Compar…
Low-complexity Design for Beam Coverage in Near-field and Far-field: A Fourier Transform Approach
Chao Zhou, Changsheng You, Cong Zhou +3
In this paper, we study efficient beam coverage design for multi-antenna systems in both far-field and near-field cases. To reduce the computational complexity of existing sampling…
Near-field Physical Layer Security: Robust Beamforming under Location Uncertainty
Chao Zhou, Changsheng You, Cong Zhou +2
In this paper, we study robust beamforming design for near-field physical-layer-security (PLS) systems, where a base station (BS) equipped with an extremely large-scale array (XL-a…
Frequency-switching Array Enhanced Physical-Layer Security in Terahertz Bands: A Movable Antenna Perspective
Cong Zhou, Changsheng You, Chao Zhou +4
In this paper, we propose a new frequency-switching array (FSA) to enhance the physical-layer security (PLS) in the presence of multiple eavesdroppers (Eves), where the carrier fre…
Near-field Target Localization: Effect of Hardware Impairments
Jiapeng Li, Changsheng You, Chao Zhou +2
The prior works on near-field target localization have mostly assumed ideal hardware models and thus suffer from two limitations in practice. First, extremely large-scale arrays (X…
