This paper introduces a novel approach for direction of arrival (DOA) estimation utilizing hybrid digital and analog phase alignment (HDAPA) tailored for hybrid analog and digital massive multiple‐input multiple‐output (MIMO) receive arrays. To address the inherent high complexity associated with traditional HDAPA and analog phase alignment methods ...
