A Simple Cross Correlation Switched Beam System (XSBS) for Angle of Arrival Estimation
IEEE Access, 2017 We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with a single radio frequency ...
