Together with the optimal linearization technique, an extended-Kalman-filter-based chaotic communication is first proposed in this paper. First, the optimal linearization technique is utilized to find the exact linear models of the chaotic system at operating states of interest. Then, an extended Kalman filter (EKF) algorithm is used to estimate both the parameters and states where the message is already embedded. By using the EKF together with the optimal linear model, the message can be recovered well at the receiver's end. Numerical examples and simulations are given to show the effectiveness of the proposed methodology.
