Comparison of nonparametric frequency estimators
2010 IEEE Instrumentation & Measurement Technology Conference Proceedings, 2010This paper deals with the performance of several up-to-date nonparametric frequency estimators. The algorithms of frequency estimation are introduced and their bias, standard deviation and consumption time are compared with regard to the most common signal parameters.

On cyclic spectrum estimation with estimated cycle frequency
2016 24th European Signal Processing Conference (EUSIPCO), 2016The problem of cyclic spectrum estimation for almost-cyclostationary processes with unknown cycle frequencies is addressed. This problem arises in spectrum sensing and source location algorithms in the presence of relative motion between transmitter and receiver.

Estimating the frequency of a periodic function
Biometrika, 1991SUMMARY The problem of estimating the frequency and other parameters of a cyclical oscillation is considered, where the data consists of a periodic function observed subject to stationary additive noise. An estimation procedure is proposed and the asymptotic properties of the estimators established.

A simple frequency rate estimator
International Conference on Acoustics, Speech, and Signal Processing, 2003Frequency-rate estimation of a linearly frequency modulated signal is addressed. A simple estimation procedure that yields accurate estimates for moderately high signal-to-noise ratios is proposed. By transforming the original sequence into a sequence that is the phase data differenced twice, the problem becomes equivalent to estimating a constant in ...

Abstract Numerical methods have been used for fitting sinusoids to data since the middle of the 18th century. Since the discovery of the Fast Fourier Transform by Cooley and Tukey in 1965, the techniques for estimating frequency have become computationally feasible.

On frequency estimation with the IQML algorithm
IEEE Transactions on Signal Processing, 1994A popular implementation of the KiSS/IQML algorithm for frequency estimation applies an inappropriate constraint to the parameter vector. This results in high thresholds for certain frequency configurations. By applying a consistent constraint, a better estimator can be obtained. >

Comparison of estimators for frequency offset
IEEE Transactions on Communications, 1990A model is proposed for errors that occur in estimating frequency offset between oscillators driving two clocks that are synchronized with a digital control loop. Three specific estimators are analyzed. One, the maximum-likelihood estimator, yields a minimum-mean-square estimate for Gaussian errors.

Among the many outstanding contributions which Ted Hannan made to Time Series Analysis his interest in the problem of detecting and estimating the frequencies of periodic components was a recurrent theme. He first discussed this topic in his early monograph [Han60], and he continued his studies throughout his research career, his final papers appearing

Estimating Word-Association Frequencies
Psychological Reports, 196814 Ss were given the 6 strongest associates to stimulus words chosen from the Kent-Rosanoff list and asked to estimate the frequency with which each associate occurred. The results indicate a striking tendency for Ss to match the obtained norms throughout the portions of the hierarchy tested.
