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

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.
