Learning or Modeling? Virtual XL-RIS Observation Reconstruction for Near-Field Sensing
Tuo Wu, Jie Tang, Jiacheng Wang +5
A passive extremely large-scale reconfigurable intelligent surface (XL-RIS) offers a position-sensitive aperture for near-field sensing, but its element-wise signals are not direct…
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
