Chaos synchronization with signal distortion in a communication channel: Experiment and numerical simulation

The effect of filtering properties of a communication channel on dynamic regulations and synchronization of oscillations in a system of two unidirectionally coupled generators of chaotic signals is studied in natural radiophysics and numerical experiments. The amplitude and phase relations between the signals of the trailing and leading systems are studied for varying transmission band of the filter and the extent of signal attenuation in the communication channel. The results of measurements are confirmed by calculations of the coherence function and variance of the phase difference of oscillations.
