A new information transfer scheme based on phase modulation of a carrier chaotic signal

Zhalnin Aleksej Jurevich, Saratov Branch of Kotel`nikov Institute of Radiophysics and Electronics of Russian Academy of Sciences

A new information transfer scheme based on dynamical chaos is suggested. An analog carrier signal is generated by self­exciting chaotic generator in a phase­coherent oscillatory regime. This carrier undergoes a modified procedure of phase modulation by information signal, which simultaneously affects upon the transmitting generator via the feedback loop. After the communication channel is passed, the signal modulated by information acts upon a receiving generator, so that a synchronous chaotic response arises in it. For data mining, a special procedure of phase detection for chaotic signal is developed. An efficiency of the scheme is demonstrated by the examples of coupled modified Rossler oscillators in the regime of spiral  chaos, and by the example of coupled self­contained generators of structurally stable (hyperbolic) chaos.
