UAV Fluid-Antenna Channel Acquisition under Intra-Scan Channel Aging
Yuanhui Wu, Hao Jiang, Liang Wu +1
Sequential sounding in UAV fluid-antenna systems (FASs) provides additional spatial information but delays transmission, causing earlier channel observations to age. This paper add…
EM-Guided Graph Learning for Fluid Antenna Beamforming under Current-Domain Constraints
Yuanhui Wu, Hao Jiang, Zaichen Zhang
Fluid antenna arrays (FAAs) reconfigure a finite set of radiating ports within a prescribed aperture. In compact apertures, however, channel-driven placement may cluster ports, str…
Impedance-Aware Zonal Port Activation for Fluid Antenna Arrays
Yuanhui Wu, Hao Jiang, Zaichen Zhang
Fluid antenna array (FAA) activation jointly determines the effective multi-user channel for precoding and the sparse physical aperture. Channel-oriented selection can concentrate…
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…
Peak Sidelobe Suppression in Planar Fluid Antenna Array
Haoyu Liang, Zhentian Zhang, Yuanhui Wu +3
Fluid antenna systems (FAS) have emerged as a promising technology for next-generation wireless communications, offering inherent reconfigurability and spatial adaptability. A dist…
