Abstract:
|
TFPF is a tool for signal enhancement, applicable to a large class of signals if
the windowed WVD TFPF is used for reduced bias. This class includes those
signals which may be represented as a sum of band-limited non-stationary processes
in additive WGN. Testing on simulated and real data indicates that the method
significantly enhances signals of this class by filtering out most of the additive noise.
Further details of the time-frequency peak filtering method are provided in [8]. |

Description:
|
This Article presents the TFPF as a tool for signal enhancement, applicable to a large class of signals if the windowed WVD TFPF is used for reduced bias. This class includes those signals which may be represented as a sum of band-limited non-stationary processes in additive WGN. Testing on simulated and real data indicates that the method significantly enhances signals of this class by filtering out most of the additive 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). |
