Rotatable Antenna-Enabled Space-Air-Ground Integrated Networks: Opportunities and Challenges
Yanhua Tan, Beixiong Zheng, Tiantian Ma +6
Space-air-ground integrated networks (SAGINs) are expected to support ubiquitous three-dimensional (3D) communication and sensing services in future sixth-generation (6G) wireless…
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-Enabled Satellite Communication: Joint Design of Boresight Alignment and Beam Tracking
Tiantian Ma, Beixiong Zheng, Changsheng You +2
Low Earth orbit (LEO) satellite links experience rapid angular variation due to high orbital velocities, which causes severe beam misalignment and array gain degradation under conv…
Movable-Antenna-Enhanced ISAC: Optimal Antenna Trajectory and Beamforming Design
Yifei Wu, Dongfang Xu, Derrick Wing Kwan Ng +2
Integrated sensing and communication (ISAC) is a key enabling technology for next-generation wireless networks. However, most existing ISAC systems rely on fixed-position antennas,…
