Reconfigurable Intelligent Surface Aided Sparse DOA Estimation Method With Non-ULA
Peng Chen, Zihan Yang, Zhimin Chen +1
The direction of arrival (DOA) estimation problem is addressed in this letter. A reconfigurable intelligent surface (RIS) aided system for the DOA estimation is proposed. Unlike tr…
