Kernel 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 ...
متن کاملInstantaneous frequency estimation using the reassignment method
This paper explores the method of reassignment for extracting instantaneous frequency attributes from seismic data. The reassignment method was rst applied to the spectrogram by Kodera, Gendrin and de Villedary [5] and later generalized to any bilinear time-frequency or time-scale representation by Auger and Flandrin [1]. Key to the method is a nonlinear convolution where the value of the convo...
متن کاملThe Instantaneous Frequency Estimation In Rotating Machinery
Stages of run-up or run-down of rotating machinery are unstable random process. The methods of time-frequency analysis, such as short time Fourier transform, wavelet transform and so on, will be employed to analyze the relevant test signals. To obtain the laws of the instantaneous frequency of multi-component signals during the run-up or run-down periods, the method based on peak search is wide...
متن کاملOverview of Signal Instantaneous Frequency Estimation Methods
This paper gives an overview of existing instantaneous frequency (IF) estimation methods divided into several major categories. One of the first IF estimation approaches was based on the spectrogram, the resolution of which is highly window size dependant. In order to improve the IF estimation accuracy, the iterative method was proposed, such that each iteration gives more accurate estimation o...
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...
