Software: Discrete wavelet transform analysis (WPLW)

A Nice Software package for Discrete Wavelet Transform Analysis (WPLW)

I am a researcher, trying to apply Wavelets to compress ECG data. For the past
6 months, I have been working with a package called WPLW (Wavelet Packet
Laboratory for Windows) to do my research. I do very strongly recommend this
tool for researchers who do not want to write their own code for wavelet
analysis. The WPLW is very user friendly, and runs under windows. It has a
library of Daubechies, Coifman, and several localized trignometric functions.
It is very simple to use, yet very powerful, in that the user can verify
multiple transcriptions and the choose the best basis, automatically. (the
best basis is chosen based on minimum entropy). The tool gives you the wavelet
packet and wavelet transform analysis. I have had very good success with this
tool, as I can very quickly do multiple wavelet filter analysis, and the
choose the best one that fits the signal of interest.

For those of you that are interested in more information, you could contact
the distributor
A K Peters, Ltd.
289 Linden St.
Wellesley, MA 02181-5910
(617) 235-2404

The best part of it all, is the outstanding technical support for this tool,
provided by Digital Diagnostic Co. in CT. It continues to be a pleasure
dealing with the folks at DDC, who support WPLW.
