Abstract

The problem of information transmitting using chaotic signals is considered. New method of information coding by means of frequency modulation of the chaotic signal is proposed. Chaotic generator is modulated by information signal by means of its time scaling. The receiver recovering algorithm, using ideas of Lion´s and speed-gradient method, based on the adaptive identification procedure and augmented signals is built up. Robustified adaptation law applicable for noisy transmission channel is presented. The example of signal transmission by means of the frequency modulation of the Chua system is given. The simulation results for signal transmission of the audio frequency range signals are demonstrated.
