Communication System Based on Chaotic Time-Delayed Feedback Generator

We study communication systems based on chaotic time-delayed feedback generator. The aim of the study is a comparative assessment of the noise immunity for the four different communication systems at the same levels of the external noise. It is shown that the principle of correlation receiver, which is used in classical communication systems, can be also used in the case where chaotic signals generated by self-oscillating systems with complex behavior are used as reference signals. Systems based on the correlation receiver principles have very high immunity to the external noise.
