Signal processing via synchronized chaotic systems with feedback control

In this paper we focus on the transmission of information signals via chaotic oscillations. To this end, we consider systems which contain generators with additional control loop and could behave chaotically and which dynamics may be controlled using feedback or directional coupling. Below we discuss three schemes of signal transmission and detection using 1) phase or frequency controlled generators, 2) coupled Chua´s circuits with the adaptive parameter control, and 3) direction-ally coupled generators extracting binary signal from chaos in a presence of noise. New capabilities of conventional control systems for producing and processing chaotic signals are very promising — both for individual use and for implementation in networks [Shalfeev et al, 94].
