Communication systems with correlation receiver based on generators with dynamical chaos

Background and Objectives: The object of research is communication systems based on the methods of correlation receiving. The aim of the study is a comparative assessment of the noise immunity of three different information transmission systems at the same levels of external noise. Materials and Methods: The methods of numerical simulation of time-delay systems are used. For the self-oscillating systems with delay, the approach based on correlation receiving is used for communication systems. Results: It is shown that the principle of correlation receiver, which is applied in classical communication systems, can also be used in the case when chaotic signals generated by self-oscillating systems with complex behavior are taken as reference signals. Conclusion: The noise immunity of the communication system based on the methods of correlation receiving and dynamical chaos is close the noise immunity of a classical communication system.
