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…
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…
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,…
Performance Scaling Laws for PD Array-based Receivers in IM/DD Optical Wireless Communication Systems
Aravindh Krishnamoorthy, Robert Schober, Harald Haas
We study the performance scaling laws for electrical-domain combining in photodetector (PD) array-based receivers employing intensity modulation and direct detection, taking into a…
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)…
