An Approach for Chaos Synchronization Based on Non-Continuous “Excursion-Orbit” Coupling

In this paper an approach is proposed for synchronizing chaotic systems, taking the viewpoint of a special characterization of chaotic attractors in which spiraling and excursion orbits are identified as the basic constituents. The proposed synchronization method takes advantage of the fact that a chaotic attractor is strongly characterized by excursion orbit segments, and hence synchronization can be achieved by coupling only the excursion orbit segments. Furthermore, a multiplexing scheme can be applied to the drive signals. Since the systems remain uncoupled for most of the time, the bandwidth required for transmitting the drive signal can be very small.
