This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of time series models has been well developed over the last thirt,y years. Both the frequenc.y domain and time domain approaches have been widely used in the analysis of linear time series models. However. many physical phenomena cannot be adequately represented by linear models; hence the necessity of nonlinear models and higher order spectra. Recently a number of nonlinear models have been proposed. In this monograph we restrict attention to one particular nonlinear model. known as the "bilinear model". The most interesting feature of such a model is that its second order covariance analysis is ve~ similar to that for a linear model. This demonstrates the importance of higher order covariance analysis for nonlinear models. For bilinear models it is also possible to obtain analytic expressions for covariances. spectra. etc. which are often difficult to obtain for other proposed nonlinear models. Estimation of bispectrum and its use in the construction of tests for linearit,y and symmetry are also discussed. All the methods are illustrated with simulated and real data. The first author would like to acknowledge the benefit he received in the preparation of this monograph from delivering a series of lectures on the topic of bilinear models at the University of Bielefeld.

Book excerpt: Estimates of the power spectral density have been found to be very useful in a variety of signal processing applications over the last several decades. Higher order spectral contain information not present in the power spectrum and recently, estimates of higher order spectral have been shown to be useful in certain signal processing problems. In particular, estimates of the bispectrum and bicoherence have been found useful in detecting non-Gaussianity and non-linearity, in system identification, and in detecting transient signals. This paper is concerned with the estimation of the bispectrum and bicoherence of underwater acoustic signals. We first introduce and describe some of the properties of the bispectrum and bicoherence. The bispectral estimation algorithm as implemented here at the Marine Physical Laboratory is then described in detail. Finally, several bispectra are estimated from actual data and the results are analyzed. In the results portion of the paper we concentrate on three particular properties of bispectrum estimation. We show how the bispectrum estimate can be used to detect non-Gaussianity, non-linearity, and harmonic coupling. The detection of harmonic coupling is shown to be a useful property of the particular bispectrum estimation algorithm employed here. (AN).

This book was released on 2014-12-11 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: By studying applications in radar, telecommunications and digital image restoration, this monograph discusses signal processing techniques based on bispectral methods. Improved robustness against different forms of noise as well as preservation of phase information render this method a valuable alternative to common power-spectrum analysis used in radar object recognition, digital wireless communications, and jitter removal in images.

Book Synopsis Estimates of the Bispectrum of Stationary Random Processes by : John Winslow Van Ness
Download or read book Estimates of the Bispectrum of Stationary Random Processes written by John Winslow Van Ness and published by . This book was released on 1964 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently interest has arisen in applications of higher order spectra and in particular in the bispectrum. Various nonlinear effects in random phenomena are studied. The bispectrum has been in Connection with oceanographic problems, among which a number of interesting phenomena such as surf beats, wave breaking, and the energy transfer between wave components can be explained only by the nonlinearity of the wave motion. The present paper discusses the bispectrum itself, some of its properties, and some assumptions on it and on the process. Intuitive reasons for choosing an estimate of the form discussed here are then given along with some convenient expressions for this estimate. Further explanation is given for the concept of cumulant functions of the process, and the statistical properties of various estimates; that is with the asymptotic bias, second-order moments, and distribution of three estimates: (1) the thirdorder moment estimate, (2) the weighted bispectral density (the bispectral distribution function) estimate, and finally (3) the estimate of the bispectral density itself.

Book excerpt: Significant results have been obtained to develop a new family of identification procedures for non-Gaussian white noise driven linear, time-invariant, nonminimum phase systems based on parametric modeling of higher-order cumulants using (i) non-causal Auto regression, (ii) forward-backward ARMA and (iii) cepstral modeling approaches. A new approach was developed to time delay estimation in the presence of spatially correlated noise and have extended the results to a general array processing problem. (jhd).
