Channel Map-Based Channel Estimation for Near-Field UM-MIMO with Movable Planar Arrays
Accurate channel estimation is essential for coherent transmission in ultra-massive multiple-input multiple-output (UM-MIMO) systems, where near-field propagation and high-dimensional spatial channels impose substantial signal processing challenges. Movable antenna architectures increase the estimation complexity furth...
