A Simple Angle of Arrival Estimation System [PDF]
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017 We propose a practical, simple and hardware friendly, yet novel and very 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 chain. Our system cross correlates a reference omni-directional signal with a set of received directed
