时滞混沌系统的参数辨识及其在保密通信中的应用

Parameter estimation of time-delay chaotic system and its application in secure communication

对系统中未知参数的辨识问题进行了系统的研究。给出了参数估计器存在的充分条件。然后,在发射端尝试将明文信号对系统的参数进行调制,在接收端利用提出的参数辨识方法来解调,从而实现数字信号的超混沌保密通信。最后数值仿真验证了该方法的有效性。

Systematic research was done on the unknown parameter estimation of the system. The sufficient condition of the existence of the parameter estimator was given. The plain text signal was modulated into the system parameter in the emitter. In the receiver, the proposed parameter estimation method was used for the demodulation. Then, the super chaos secure communication was realized. Finally numerical simulations were given to verify the effectiveness of the proposed approach.
