چکیده

Abstract Modi ed covariance Pisarenko harmonic decomposition and reformed Pisarenko harmonic decomposition methods are three closed form frequency estimators which are derived from the linear prediction property of sinusoidal signals In this paper we develop the recursive least squares type realizations of these estimators for a single real tone and their frequency tracking performances are contrasted via computer simulations

Comparative tracking performance of the LMS and RLS algorithms for chirped narrowband signal recovery

This paper studies the comparative tracking performance of the recursive least squares (RLS) and least mean square (LMS) algorithms for time-varying inputs, specifically for linearly chirped narrowband input signals in additive white Gaussian noise. It is shown that the structural differences in the implementation of the LMS and RLS weight updates produce regions where the LMS performance excee...
