Ooooh, I love it....the blind (somebody who doesn't understand the problem)
leading the blind (a neural net).

Nothing personal......but wouldn't it make more sense to do NN research with 
a problem that you understand?

If not, check out Ron Cole's paper in the Albuquerque ICASSP (1990).
He compares several different representations as input to a NN.  Your data
isn't necessarily bad, but your representations are't robust in the
face of noise.  Also check out Melvyn Hunt's paper in the NY ICASSP.
