ABSTRACT:
For recognizing information conveyed by a received signal, represented by convention by possible elementary forms of the signal to be transmitted, a device includes a correlator for establishing a correlation between the received signal and various possible forms of signal, in accordance with the convention. A neural network using correlation coefficients obtained from the correlator is trained by application to its input of correlation coefficients corresponding to a received signal conveying given information whilst imposing the given information at its output. The network supplies recognized information.
