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…
Near-field Beam Training under Multi-path Channels: A Hybrid Learning-and-Optimization Approach
Jiapeng Li, Changsheng You, Guoliang Cheng +3
For extremely large-scale arrays (XL-arrays), the discrete Fourier transform (DFT) codebook, conventionally used in the far-field, has recently been employed for near-field beam tr…
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…
Codebook Design for Limited Feedback in Near-Field XL-MIMO Systems
Liujia Yao, Changsheng You, Zixuan Huang +3
In this paper, we study efficient codebook design for limited feedback in extremely large-scale multiple-input-multiple-output (XL-MIMO) frequency division duplexing (FDD) systems.…
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…
A Tutorial on MIMO-OFDM ISAC: From Far-Field to Near-Field
Qianglong Dai, Yong Zeng, Huizhi Wang +10
Integrated sensing and communication (ISAC) is one of the key usage scenarios for future sixth-generation (6G) mobile communication networks, where communication and sensing (C&S)…
