Learning or Modeling? Virtual XL-RIS Observation Reconstruction for Near-Field Sensing
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 directly observed. Recovering this virtual RIS observation (VOR) from fewer base-station measurements requires prior information. This paper inves...
