Noninvertible Maps

This paper deals with a new coding scheme in digital implementation for secure communications. It is based on specific dynamic features generated by noninvertible maps. The main results are a global chaos synchronization, an exact synchronization without a residual error generated by the classical methods, a robustness with respect to channel disturbances. Chaos synchronization is obtained by introducting an observer model and the classical results of the control theory. Besides, this coding scheme introduces several "keys" required for decoding the initial information, which improves the security of communications.

In this paper the problem of chaos synchronization, and the related phenomena of riddling, blowout and on–off intermittency, are considered for discrete time competition models with identical competitors. The global properties which determine the different effects of riddling and blowout bifurcations are studied by the method of critical curves, a tool for the study of the global dynamical properties of two-dimensional noninvertible maps. These techniques are applied to the study of a dynamic market-share competition model.

Chaos synchronization of delayed quantum dot light emitting diode has been studied theortetically which are coupled via the unidirectional and bidirectional. at synchronization of chaotic, The dynamics is identical with delayed optical feedback for those coupling methods. Depending on the coupling parameters and delay time the system exhibits complete synchronization, . Under proper conditions, the receiver quantum dot light emitting diode can be satisfactorily synchronized with the transmitter quantum dot light emitting diode due to the optical feedback effect.
