Studied James S. Walker's aprimer on wavelets and their scientific
applications.
but I am wondering where I can make use of it.

Just curious.

Hi, I am sure people here will give you hundreds of uses of wavelets. One
thats spring to mind (from a computer graphics/vision approach) is image
compression. See the JPEG2000 compression algorithm. It uses wavelets.

Regards,
V.Z.

Yeah, I was aware that. The book I am reading gave a lot of examples in
image
compression and noise reduction, which could be found in photoshop also.

I am wondering whether I could make use of that in the wireless modulation
and
demodulation.

Thanks.

IS used, and will be used extensively over networks or otherwise.

This you can all do on your PC.
I have tested snow codec BTW last weeek, it is not ready for primetime
(or replacement of mpeg2, and DCT based codecs).
See my posting on rec.video.desktop.
So, as you may now see, wavelet is here, and people are using it.
And source code is available.

I moved your response to the end, so that future readers can make
sense of the thread.

If it is like other JPG algorithms, they are lossy. Our brains
can make sense of a JPG image, since a lot of information in a
photograph is redundant, and "close enough is good enough". This
won't work for network traffic, because the slightest errors can
affect routing information, and other integrity-critical
information.

Not exactly, when we for example look at vector oriented modulation systems,
QAM, you see there is a 'tolerance' (of the area) were the vector has to point
for it to be a for example '11' 01' etc..
Given this 'fuzziness' (on the border of analog and digital), why not?
He is talking 'modulation' and 'demodulation' after all.
