Chaotic switching system using mixed-mode chaotic circuit

We present a new chaotic switching system for transmission of digital signals via a mixed-mode chaotic circuit which has both autonomous and nonautonomous chaotic dynamics via a switching method. In the transmitter based on mixed-mode chaotic circuit, a digital information signal and its inverse signal control two switches whose complementary actions change the chaotic mode of transmitter. The receiver consists of two synchronous chaotic subsystems whose chaotic regimes are of different modes. In this system, we used the idea of one-way coupling technique to observe chaos synchronization between the transmitter and the receiver. The static and dynamic performances of the system have been investigated and simulation results verify our approach
