CSI Reconstruction in Fluid Antenna Systems Without Spatial Covariance Priors
Zhentian Zhang, Kaitao Meng, Tuo Wu +6
Fluid antenna systems (FASs) exploit many candidate ports for spatial diversity, but hardware constraints allow channel observations at only a few active ports. Whether full-port C…
Geometry-Aware Resource Allocation for Network-Level ISAC Systems
Xiao-Yang Wang, Luting Kong, Lei Cao +7
Network-level integrated sensing and communication (ISAC) is recognized as a transformative technology for next-generation mobile radio systems. By enabling collaboration among mul…
AI Empowered Communication and Radar Modulation Recognition: A Survey
Wei Huang, Pengfei Zhang, Huai Qin +4
Automatic modulation recognition (AMR) is of vital importance for ensuring communication and radar reliability, efficient spectrum utilization and resistance to electronic interfer…
Constellation Selection and Power Allocation for Multi-Cell OFDM-ISAC: Managing Inter-Cell Interference and Sensing Sidelobes
Kaitao Meng, Kawon Han, Christos Masouros +1
Future integrated sensing and communication (ISAC) networks are expected to operate in dense multi-cell environments, where multiple base stations (BSs) share their time-frequency…
Finite-Blocklength ISAC Multiple Access: A Source-Channel Coding Perspective
Zhentian Zhang, Kaitao Meng, Hao Jiang +1
Future networks must serve massive populations of devices that sense and communicate simultaneously under short-packet constraints, yet the fundamental limits of integrated sensing…
Spatial Modulation for Tx-SIMO-FAS: Port Selection and Performance Analysis
Xusheng Zhu, Kai-Kit Wong, Hanjiang Hong +2
This paper considers a single-input multiple-output (SIMO) setup with a fluid antenna system (FAS) at the transmitter side and multiple fixed antennas at the receiver, which is ref…
