Synchronizing hyperchaotic systems with several non-linearities: observer design and time-division multiplexing of the scalar signal

This paper deals with hyperchaos synchronization via a scalar signal. By exploiting observer design and time-division multiplexing of the transmitted signal, a novel framework for synchronizing hyperchaotic circuits with one or several non-linearities is proposed. The approach is successfully applied to 8^th order circuits with one non-linearity as well as to 6^th order circuits with two non-linearities.
