Abstract :
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/sup th/ order circuits with one nonlinearity as well as to 6/sup th/ order circuits with two nonlinearities.
