Generalized frequency estimator with rational combination of three spectrum lines
IET Radar, Sonar & Navigation, 2022 The popular Discrete Fourier Transform (DFT) is known to be a sub‐optimal frequency estimation technique for a finite transform length. In order to approach the Cramer‐Rao Lower Bound (CRLB), many refinement techniques have been considered, but little ...

Interpolated DFT Algorithm for Frequency Estimation by Using Maximum Sidelobe Decay Windows
IEEE Access, 2022 A sinusoidal frequency estimator based on interpolated Discrete Fourier Transform (DFT) algorithm by using Maximum Sidelobe Decay (MSD) windows is proposed in this paper. Firstly, the received sinusoid is weighted by an appropriate MSD window.

A convergent frequency estimator [PDF]
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000 Online identification of sinusoidal components is an important problem that occurs in active noise control, vibration suppression, online health monitoring, and radar, sonar, and seismic applications. We adopt an approach to this identification problem which consists of the utilization of the underlying nonlinearity and an algorithm that is based on ...
