Empirical Studies of Propagation Characteristics and Modeling for Extremely Large-Scale MIMO Channels: From Near-Field to Far-Field

This work systematically investigates the channel measurements and modeling for the emerging near-field radio communications (NFRC) in extremely large-scale MIMO (XL-MIMO) systems. It provides empirical insights and modeling approaches for the spatial non-stationary characteristics of XL-MIMO channels from near-field to far-field.
