dc.description (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 methodology based on a resolution performance measure P for time-frequency distributions (TFDs) was defined to optimise TFDs and select the one which results into best concentration of signal components around their instantaneous frequency laws, and best suppression of the interference terms in the time-frequency plane. The algorithm which implements this methodology is described by Sucic and Boashash (see Proceedings of the IEEE International Conference on Acoustics, Speech and Signal Processing-ICASSP'01, Salt Lake City, Utah, USA, May 2001). In this paper we investigate the performance and robustness of the algorithm for multicomponent signals of linear and non-linear FM laws. We also study its applicability to signals with more-than-two components at different distances from each other, as well as the two-component signals with non-equal amplitudes of the components' mainlobes. en_US
