In recent years, there has been a strong interest in low-power low complexity localization systems based on the electromagnetic properties of the interacting signals. Reducing power and complexity are key requirements especially for the fast-growing number of applications based on the Internet of Things (IoT) paradigm. In this paper we propose a novel technique for the Angle of Arrival estimation based on phase interferometry. The technique is fully digital and synchronous and its major advantage relies on the simple hardware implementation and modularity. The approach was validated on a Cyclone IV E EP4CE115F29C7 FPGA and showed very promising preliminary results.

Abstract
In recent years, there has been a strong interest in low-power low complexity localization systems based on the electromagnetic properties of the interacting signals. Reducing power and complexity are key requirements especially for the fast-growing number of applications based on the Internet of Things (IoT) paradigm. In this paper we propose a novel technique for the Angle of Arrival estimation based on phase interferometry. The technique is fully digital and synchronous and its major advantage relies on the simple hardware implementation and modularity. The approach was validated on a Cyclone IV E EP4CE115F29C7 FPGA and showed very promising preliminary results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
