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…
Rotatable IRS-Assisted 6DMA Communications: A Two-timescale Design
Chao Zhou, Changsheng You, Cong Zhou +4
Intelligent reflecting surface (IRS) and movable antenna (MA) are promising technologies to enhance wireless communication by reconfiguring channels at the environment and transcei…
MA-enhanced Mixed Near-field and Far-field Covert Communications
Chao Zhou, Changsheng You, Cong Zhou +2
In this paper, we propose to employ a modular-based movable extremely large-scale array (XL-array) at Alice for enhancing covert communication performance. Compared with existing w…
