CODING THE CHAOS IN A SEMICONDUCTOR DIODE FOR INFORMATION-TRANSMISSION

A variety of dynamic states can be created from chaos by using a weak periodic perturbation. Since these states can be further classified by some characteristic index, here the Shannon entropy, we suggest that a temporal programming of small parameter switching between these dyna mic states can lead to a new mean of message coding without greatly mo difying the system. Thus a unique scheme of information transmission c an be achieved by way of coding chaos based on the Shannon entropy cha racterization. We demonstrate experimentally the proposed scheme in a semiconductor diode.
