Description

Neuromorphic classification of RF-Modulation type is an on-going topic
in SIGINT applications. Neural network training approaches are varied,
each being suited to a certain application. For exemplification I show
the results for BFGS (Broyden-Fletcher-Goldfarb-Shanno) optimisation
in discriminating AM vs FM modulation and of stochastic optimisation
for the challenging case of AM-LSB vs. AM-USB discrimination. Although
slower than BFGS, the stochastic training of a neural network avoids
better local minima, obtaining a stable neurocore.
