CSI-Free Deep Learning-Based Hardware-Aware Precoding for Wideband Near-Field THz Systems

This letter investigates hybrid analog precoding for wideband near-field terahertz (THz) ultra-massive multiple-input multiple-output (UM-MIMO) systems under beam squint and practical true time delay (TTD) and phase shifter (PS) hardware limitations. We formulate the joint optimization of TTD and PS coefficients as a n...
