Coupling Synchronization for Fractional Order Chaotic Systems and Design of Chaotic Shift Keying Communication

Fractional order chaotic system synchronization has important application value in the chaotic communication field. It studies the unidirectional coupling synchronization problem of fractional order Chen chaotic system. Based on Lyapunov stability theory of fractional order chaotic system,design a single variable linear coupling synchronization controller,and realize the fractional order Chen chaotic system coupling synchronization. Apply the fractional order Chen chaotic synchronization system to design the chaotic shift keying communication system,and analyze the bit error rate performance of the system. It is shown that the fractional order chaotic communication system is more secure than the integer order one,and their performances to resist noise are almost same.
