Adaptive ESPRIT algorithm based on the PAST subspace tracker

Abstract : The Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) algorithm is a subspace-based analysis method used in source localization or frequency estimation, originally designed in a block signal processing context. In other respects, the Projection Approximation Subspace Tracker (PAST) is a fast and robust subspace tracking method. This paper introduces a new frequency estimation and tracking algorithm, which relies on the PAST subspace tracker and a fast adaptive implementation of the ESPRIT algorithm.
