Abstract:
|
This Article shows that for random non-stationary signals, by taking the expectation value of the PWVD, one obtains a definition of time-varying higher-order spectra (TVHOS), which extends both time-frequency distributions and higher-order spectral analysis to define an effective tool for the analysis of FM signals affected by additive and/or multiplicative noise. |

Description:

This Article shows that for random non-stationary signals, by taking the expectation value of the PWVD, one obtains a definition of time-varying higher-order spectra (TVHOS), which extends both time-frequency distributions and higher-order spectral analysis to define an effective tool for the analysis of FM signals affected by additive and/or multiplicative noise.
(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). |
