DoA Estimation in Python using MUSIC and ESPRIT Algorithms

less than 1 minute read

Published:

Here, We consider the Direction of Arrival (DoA) estimation using the Multiple Signal Classification (MUSIC) and Estimation of Signal Parameters via Rotational Invariance Technique (ESPRIT) algorithms. DoA estimation finds a lot of applications in wireless positioning, target tracking and MIMO channel estimation etc. MUSIC and ESPRIT are two popular techniques for such problems. ESPRIT is more computationally efficient than MUSIC. The code is available here.
