Sparse Port Selection under Mutual Coupling in Fluid Antenna Arrays
Jingyuan Xu, Haoyu Liang, Zaichen Zhang +1
Fluid antenna systems obtain spatial degrees of freedom by reconfiguring antenna positions within a confined region, a principle that extends to beamforming: shaped beams can be sy…
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…
Fluid-Antenna-Aided Active User Detection With 1D-CNN Channel Reconstruction for Unsourced Random Access
Haoyu Liang, Zhentian Zhang, Hao Jiang +2
In this paper, we investigate the application of fluid antenna systems (FAS) for active user detection (AUD) in unsourced random access (URA). A channel reconstruction method based…
Neural Networks-Enabled Channel Reconstruction for Fluid Antenna Systems: A Data-Driven Approach
Haoyu Liang, Zhentian Zhang, Jian Dang +2
Fluid antenna systems (FASs) offer substantial spatial diversity by exploiting the electromagnetic port correlation within compact array spaces, thereby generating favorable small-…
