I have implemented two new experimental features to improve CW
detection and decoding capabilities in FLDIGI softare.
1) Matched Filter feature improves signal-to-noise making barely
audible morse code detection to work better in FLDIGI CW mode.
2) Self Organized Map feature is using an artificial neural network
algorithm from SOM (see http://en.wikipedia.org/wiki/Self-
organizing_map )
to calculate best matching codebook entry from input vector using
Euclidian distance method.
I have documented these experimental features in my blog as well as
test results:

The software is pre alpha quality and not ready for broader
distribution.
If you have interest in testing/improving this software let me know.
