Nonstationary sinusoidal modeling with efficient estimation of linear frequency chirp parameters
We present an enhanced sinusoidal modeling system that efficiently parameterizes spectral peaks by linear frequency chirp rate, in addition to the standard parameters of amplitude, center frequency, and phase. Similar to a conventional sinusoidal modeling systems, the current system operates in a frame-by-frame manner, but also efficiently obtains a chirp parameter estimate for each peak in a g...
متن کامل2D sinusoidal amplitude estimation with application to 2D system identification
In a companion paper [1], we studied amplitude estimation of one-dimensional (1-D) sinusoidal signals from measurements corrupted by possibly colored observation noise. We herein extend the results for twodimensional (2-D) amplitude estimation, which is of interest in various applications, including medical imaging, synthetic aperture radar (SAR), seismology, and many others. In particular, we ...
متن کاملSinusoidal frequency estimation by signal subspace approximation
Eigenvector-based methods such as multiple signal classification (MUSIC) are currently popular in sinusoidal frequency estimation due to their high resolution. A problem with these methods is the often high cost of estimating the eigenvectors of the autocorrelation matrix spanning the signal (or noise) subspace. In this work, we propose an efficient Fourier transform-based method avoiding eigen...
متن کاملAdaptive time delay estimation for sinusoidal signal
An adaptive algorithm is proposed for time delay estimation between sinusoidal signals received at two spatially separated sensors. The idea is to model the differential delay by an FIR lter whose coe cients are samples of a sine function. The delay estimate is updated directly on a sample-by-sample basis using the least mean square method and its convergence behavior and mean square delay erro...
متن کاملEstimation of the Parameters of Sinusoidal Signal Components and of Associated Perceptual Musical Interpretation Effects
The estimation of the parameters of a sinusoidal signal is an old problem and has been extensively studied in the literature. We propose here to use a well known method ; the estimation of the parameters by using the Fast Fourier Transform (FFT) and by taking into account the mutual influence of a part of the frequential peaks. When we extract the sinusoidal part of the signal, we obtain a nois...
