Structured Channel Estimation and Localization for Wideband Near-Field MIMO Systems
In wideband near-field multi-input multi-output (MIMO) systems, spherical-wave propagation induces a chirp-like channel structure, yet the intrinsic line-of-sight (LoS) element-wise transmit–receive coupling structure is usually neglected for improving channel estimation and localization accuracy, and the non-line-of-s...
