A LINEAR INVERSE SYSTEM APPROACH IN THE CONTEXT OF CHAOTIC COMMUNICATIONS

A chaotic signal masking scheme involving the inverse system approach which uses nonautonomous chaotic systems is presented. In this context , two simple second-order nonautonomous systems are studied to demonst rate how such forced systems can be used for private communication pur poses. The two main difficulties arising in such applications are the chaos synchronization and the exact duplication of the transmitter's n onlinear parts at the receiving end also. It is shown that our approac h overcomes such difficulties by making use of second-order forced sys tems. Examples of circuit implementations for the transmitter and the receiver subsystems are discussed to investigate different recovering techniques.
