Special Properties of Wideband Communication Based on Generators with Rough Dynamics

The article compares the efficiency of the information transmission based on the synchronization of different wideband signal generators, both in the presence of noise in the communication channel and in the conditions of frequency distortion of the signal transmitted in the communication channel. The generators of a hyperbolic chaos and a strange nonchaotic attractor, which are used in this work as generators of a signal, demonstrate complex dynamics and have a wide continuous spectrum. It was shown that the communication method based on a hyperbolic chaos is more sensitive to noise than on the generator of a strange nonchaotic attractor. The presence of a stopban in the low-frequency and high-frequency regions, however, makes it possible to detect the information with minimal distortion using communication circuits based on both generators.
