Low-Complexity Near-Field Angle–Range Localization for XL-MIMO Communications
For near-field angle–range localization in extremely large-scale multiple-input multiple-output (XL-MIMO) systems, many existing estimators for <inline-formula> <tex-math notation="LaTeX">$M$ </tex-math></inline-formula>-antenna arrays suffer from the prohibitive complexity of grid search or <inline-formula> <tex-math...
