Characterizing and Utilizing Near-Field Spatial Correlation for XL-MIMO Communication

This paper investigates the near-field spatial correlation (SC) for extremely large-scale multiple-input multiple-output (XL-MIMO) communications, where the positions of scatterers and/or users may be in the radiative near-field region due to the large size of the antenna array. Therefore, the conve...
