In this paper, we investigated a self-oscillating ring system with variation of the delay time, which demonstrates the phenomenon of laminar chaos. The presence of laminar chaos is demonstrated for various laws of time delay variation - sinusoidal, sawtooth, and triangular. The behavior of coupled systems with laminar chaos and diffusive coupling is investigated. The presence of synchronous behavior is shown.

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.
