Sparse Channel Acquisition in Aging Fluid Antenna Systems: A Reliability-Calibrated Posterior Reconstruction Approach
Xiaokai Song, Jie Tang, Tuo Wu +5
Fluid antenna systems (FASs) exploit port-domain diversity within a compact aperture, but their gain can be lost if the receiver has to scan too many ports before data transmission…
Reconfiguring Sparse Apertures: Partial-Mobility Planar FAS for 2-D DOA Estimation
Xiaokai Song, Tuo Wu, Jie Tang +3
Classical sparse arrays enlarge the sensing aperture under limited element and radio-frequency (RF) chain budgets, but their fixed geometries impose a persistent tradeoff between w…
Electromagnetic Twin: Completing the Wireless World from Sparse Channel Evidence
Tuo Wu, Jie Tang, Kangda Zhi +5
Acquiring dense channel information over many locations and beams incurs considerable pilot and processing overhead. Radio maps and channel knowledge maps (CKMs) reduce this overhe…
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…
Enormous Fluid Antenna Systems (E-FAS) for Wireless Sensing: Channel Modeling and Conditional Estimation Limits
Farshad Rostami Ghadi, Kai-Kit Wong, Jose D. Vega-Sanchez +2
In this paper, we develop a fundamental analytical framework for integrated sensing and communications (ISAC) enabled by the Enormous Fluid Antenna System (E-FAS), which transforms…
How Many Independent Modes Does a Fluid Antenna Have? A Closed-Form Outage Analysis via Equivalent Degrees of Freedom
Tuo Wu, Junteng Yao, Kai-Kit Wong +5
In a fluid antenna system (FAS), a single reconfigurable antenna is able to activate one of correlated ports to exploit spatial diversity. However, outage analysis is challengi…
