dc.description This is one of the earliest Article that presented a review of t-f detection methods using the WVD and XWVD and Time-varying higher order spectra with two applications in feature extraction and time-frequency signaturing of individual cylinder firings for classification. (Additional details can be found in the comprehensive book on Time-Frequency Signal Analysis and Processing (see http://www.elsevier.com/locate/isbn/0080443354). In addition, the most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia, and then continuously updated). en_US
dc.description.abstract A review of detection methods has been provided and it has been seen that time-frequency based detectors form an important subclass of these methods. Of the time-frequency based detectors, the WVD and XWVD based ones have been seen to be particularly useful, due to their energy preserving properties and their ability to provide good .localisation in time and frequency. Time-varying higher order spectra have also been introduced as a possible means for detection. These methods were illustrated on two applications; the first was an example of feature extraction, where the problem was to detect an unknown FM modulated signal component. The second application was in the area of time-frequency signaturing, in which the WVD was used to provide signatures for individual cylinder firings. These signatures were then able to be used for very effective classification. en_US
