Rotatable Antenna-Empowered Wireless Networks: A Tutorial
Beixiong Zheng, Qingjie Wu, Xue Xiong +11
Non-fixed flexible antenna architectures, such as fluid antenna system (FAS), movable antenna (MA), and pinching antenna, have garnered significant interest in recent years. Among…
Multiuser MIMO-AFDM Beamforming for ISAC in Doubly Dispersive Channels
Rang Liu, Ming Li, A. Lee Swindlehurst +2
Integrated sensing and communication (ISAC) in high-mobility channels requires waveform and beamforming designs that are robust to delay-Doppler dispersion. With this in mind, in t…
Antenna Orientation Optimization for Rotatable Antenna-Enabled ISAC Systems
Qingjie Wu, Beixiong Zheng, Guangchi Zhang +1
Non-fixed flexible antenna architectures, such as fluid antenna system (FAS), movable antenna (MA), and pinching antenna, have garnered significant interest in recent years. In thi…
Reliable ORIS-assisted FSO Communications via HARQ
Georgios D. Chondrogiannis, Athanasios P. Chrysologou, Vasilis K. Papanikolaou +3
This paper studies a free-space optical (FSO) link assisted by an optical reconfigurable intelligent surface (ORIS) and enhanced by a hybrid automatic repeat request (HARQ) scheme.…
Point Spread Function Optimization for Communication-assisted UAV-borne MIMO TomoSAR
Pouya Fakharizadeh, Mohamed-Amine Lahmeri, Gerhard Krieger +1
This paper tackles the optimization of the point spread function (PSF) of unmanned aerial vehicle (UAV)-borne multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) t…
Rotatable Antenna-Enhanced Cell-Free Communication
Kecheng Pan, Beixiong Zheng, Yanhua Tan +4
Rotatable antenna (RA) is a promising technology that can exploit new spatial degrees-of-freedom (DoFs) by flexibly adjusting the three-dimensional (3D) boresight direction of ante…
