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…
Modeling and Performance Analysis for Fluid Antenna System Enabled UAV Near-Field Communications
Hao Jiang, Wangqi Shi, Zhentian Zhang +3
Fluid antenna systems (FASs) offer a promising solution for unmanned aerial vehicle (UAV) air-to-ground (A2G) communications by enabling reconfigurable radiation characteristics. A…
Learned Blockwise Port Activation for Real Time Beamforming in Fluid Antenna Arrays
Yuanhui Wu, Zhentian Zhang, Hanjiang Hong +5
Fluid antenna arrays (FAAs), support multiuser downlink transmission by activating a subset of reconfigurable ports. The activation mask jointly determines the effective channel an…
Electromagnetic-Aware Fluid Antenna Array
Zhentian Zhang, Yuanhui Wu, Hao Jiang +2
Fluid antenna arrays (FAAs) offer a promising means of exploiting spatial degrees of freedom through adaptive port positioning. However, most existing communication models treat an…
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…
