Beyond Beamforming: Phase-and-Gain Channel Shaping via Rotatable Antenna Arrays
Xingxiang Peng, Qingqing Wu, Ziyuan Zheng +2
This paper investigates geometry-reconfigurable transmission for multiuser communication systems enabled by a rotatable antenna array. In contrast to conventional fixed arrays, the…
AN-Aided Secure Beamforming for ELAA-SWIPT in Mixed Near- and Far-Field
Yaqian Yi, Guangchi Zhang, Miao Cui +2
This letter investigates secure hybrid beamforming (HB) design for an extremely large-scale antenna array-aided simultaneous wireless information and power transfer (SWIPT) system…
Physical-Layer Security in Mixed Near-Field and Far-Field Communication Systems
Tianyu Liu, Changsheng You, Cong Zhou +4
Extremely large-scale arrays (XL-arrays) have emerged as a promising technology to improve the spectrum efficiency and spatial resolution of future wireless systems. Different from…
Intelligent Reflecting Surface-Aided Electromagnetic Stealth over Extended Regions
Qingjie Wu, Beixiong Zheng, Guangchi Zhang +2
Compared to traditional electromagnetic stealth (ES) materials, which are effective only within specific frequencies and orientations, intelligent reflecting surface (IRS) technolo…
