dc.description This chapter reviews TFDs and presents a high-resolution TFD, the MBD, which outperforms other TFDs in terms of (t, f) resolution for signals with closely spaced components. It applies a methodology for selecting an optimal TFD for a given real-life signal under application-specific constraints with illustration on an Australian bird song signal. (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).
dc.description.abstract This chapter presents in three interrelated sections the key concepts and techniques needed to design and use high performance time-frequency distributions (TFDs) in real-world practical applications. Section 6.1 first presents, in a heuristic approach, the core concepts forming the field of time-frequency signal processing, incorporating recent developments, such as the design of high resolution quadratic TFDs for multicomponent signal analysis. Section 6.2 outlines methods of assessment of the performance of time-frequency techniques, in terms of the resolution performance of TFDs in separating closely spaced components in the time-frequency domain. A performance measure is defined using key attributes of TFDs, such as the components' mainlobes and sidelobes, and cross-terms. This method of assessment of TFDs performance has led to improvements in designing high resolution quadratic TFD for time-frequency analysis of multi component signals. Section 6.3 presents a methodology for selecting the optimal TFD for a given real-life signal under application-specific constraints. The methodology, based on the performance measure, allows for emphasis of signal features in specific regions of interest in the time-frequency domain. en_US
