摘　　要：基于自适应误差反馈策略，利用同步误差对系统参数进行调整，并采取策略对信道噪声进行一定程度的补偿，实现了两个具有参数失配的混沌系统的同步。并在此基础上利用参数调制和参数估计策略，实现了信息传输。Based on error feedback theory,adaptively adjusting the feedback coefficient and the parameter of the received system as well as compensating the channel noise according to the synchronizing error,two chaotic systems,with the parameter mismatching,are synchronized in the ideal and channel noise environments.Numeric simulations are carried out to show the effectiveness of this method.Using the parameter modulation and the parameter estimation,a secure way of information transformation is Proposed with some good characteristics.The simulation is also proposed about this ideal.
