【Abstract】 Chua′s circuit,which is improved to integrate conveniently,is presented.A drive-response band chaotic synchronization system is constructed,which possesses to a certainly stability、resisting-disturbance and so on,at the same time,the major factors of influencing chaotic synchronization and the method of estimating bond frequency band are presented;according to FMD technique,the critical problem of how to simultaneously transmit the controlling signal of chaotic synchronization and the secret signal at a channel can be solved,and that,a practical experiment validates the method;as a result,the research in the paper provides the foundation of putting chaos into practice application to secret communication.更多还原
