MODIFIED METHOD FOR SYNCHRONIZING AND CASCADING CHAOTIC SYSTEMS

In this contribution a modification of the Pecora-Carroll [Phys. Rev. Lett. 64, 821 (1990)] one-way (or drive-response) synchronization meth od is suggested, such that both drive and response have the same dimen sionality. As a result, it is possible reproduce the driving signal wi th a single connection, increasing, thus, the number of potential conn ections of a given system. The main features of the method presented i n this work are discussed with an application to the Rossler and Loren z models [O. E. Rossler, Phys. Lett. A 57, 397 (1976); E. N. Lorenz, J . Atmos. Sci. 20, 130 (1963)], including the possibility of designing different chaotic receivers to be used in the field of secure communic ations and the setup of an array of chaotic units in which several pos sible connections are allowed for.
