Algorithms for estimating instantaneous frequency
نویسندگان
چکیده
Three algorithms to estimate instantaneous frequency of a frequency-modulated signal is discussed. These algorithms are 7 based on Hilbert transform, Haar wavelet, and generalized pencil of function (GPOF) methods. While GPOF-based frequency detection method appears to be least sensitive to noise, wavelet-based method is easiest to implement. The latter method is 9 also computationally more e cient and can be implemented in real-time. Results for both synthetic and experimental data are shown. 11 ? 2004 Elsevier B.V. All rights reserved.

Estimating and Interpreting the Instantaneous Frequency of a Signal-Part 2: Algorithms and Applications
This paper, which addresses the important issue of estimating the instantaneous frequency (IF) of a signal, is a sequel to the paper which appears in this issue, and dealt with the concepts relating to the IF. In this paper the concept of IF is extended to be able to cope with discrete time signals. The specific problem explored is that of estimating the IF of frequency modulated (FM) discrete-...

Estimation of the magnitude and frequency of maximum instantaneous discharges and hydrographs are used for a variety of purposes, such as the design of bridges, culverts, flood-control structures; and the management and regulation of floodplains. Fuller (1914), developed a flood-frequency formula based on analysis of flood peaks in hundred of streams to provide simple methods of estimating maxi...
متن کاملTechniques for Estimating the Ideal Binary Mask
This paper provides a comparison of binary mask estimation techniques, based on different ways of estimating the instantaneous SNR. The effect of six different gain functions and three noise estimation algorithms on estimating the SNR, and subsequently the binary mask was assessed. New criteria are proposed for classifying time-frequency bins as belonging to the target or masker signals. Senten...
متن کاملInstantaneous Frequency Estimation Using a Least Squares Time-Frequency Method
We present a method for estimating the instantaneous frequency of a signal. This method involves the calculation of a time–frequency energy density of the signal, then obtaining an instantaneous frequency estimate from this joint density. Time–frequency energy density is calculated as a least squares optimal combination of multi–window Gabor based evolutionary spectra. The optimal weights are o...
متن کاملKernel estimation of the instantaneous frequency
We consider kernel estimators of the instantaneous frequency of a slowly evolving sinusoid in white noise. The expected estimation error consists of two terms. The systematic bias error grows as the kernel halfwidth increases while the random error decreases. For a nonmodulated signal, g(t), the kernel halfwidth which minimizes the expected error scales as h ∼ [ σ2 N |∂2 t g |2 ]1/5 , where σ2 ...
