Secure Communication System Using Chaotic Signals

Abstract

WE PRESENT EXPERIMENTAL RESULTS OF A CHAOTIC COMMUNICATION SYSTEM THAT EMPLOYS DIRECT MODULATION, WITH THE CHUA'S CHAOTICOS CILLATOR AS A CORE OF THE TRANSMITTER BLOCK. THE MAIN RESULT IS THAT ITS POSSIBLE TO RECOVER THE INFORMATION SIGNAL IF WE MODULATE OVER ONE STATE OF OSCILATOR AND TRANSMIT A DIFFERENT STATE, AVOIDING A CORRELATION BETWEEN THE INFORMATION SIGNAL AND THE CHAOTIC CARRIER.
