The use of sliding spectral windows for parameter estimation of decaying sinusoidal signals
O'Shea, Peter J. (1997) The use of sliding spectral windows for parameter estimation of decaying sinusoidal signals. In TENCON '97. IEEE Region 10 Annual Conference. Speech and Image Technologies for Computing and Telecommunications, 2-4 December 1997.
It is quite common to model speech as the sum of a number of exponentially damped sinusoids. An example of where this is important is in the estimation and tracking of the formants of the speech. Typically, parametric spectrum analysis methods are used to estimate the parameters of the decaying sinusoids (or modes) Prony's method, Burg's method, and Pisarenko's method are some of the methods employed. This paper will present a Fourier based algorithm for estimating the parameters of damped sinusoidal components. The algorithm is based on the sliding window method of Poon and Lee (1988), but has a number of innovations

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
