Study on Analog and Discrete Chaos Oscillators Synchronization

The current work is devoted to studying the possibility of chaotic synchronization between analog and discrete chaotic systems, the parameters of which differ due to the different natures of the oscillators. The direct state variable-based synchronization (Pecora-Carrol) is investigated for analog-discrete, as well as for discrete-analog master–slave system configuration. For the study, the Vilnius chaos oscillator and its discrete model are chosen; however, this approach can be applied to other chaos oscillators. This study confirms the fundamental ability to synchronize analog and discrete chaotic systems without adjusting system parameters. The acquired results further expand the possible applications of chaos oscillators in developing hybrid communication systems for applications in wireless sensor networks (WSN).
