direction of arrival (DoA)

Direction of Arrival (DoA) or Angle of Arrival (AoA) is a function of directional antenna arrays and smart antennas, with which they determine the direction from which the received electromagnetic wave

comes. A technique used for DoA is called Multiple SignalClassification (MUSIC) and uses an algorithm

tocalculate the direction from the various received signals. Other techniques that work with the peak value of the spectrum and differ in their algorithms are Estimation of Signal Parameters

via Rotational Invariance Techniques (ESPRIT) and the Matrix-Pencil-Method. The DoA technique is used, among other things, to determine the position of objects in mobile radio networks. It can be used to display location-based services (LBS) on the smartphone display.
