A new chaos modulation communication method is proposed.An adaptive controller is used to track the error of the information signal to modulate the transmitting system of the chaotic carrier.At the same time, the information signal is directly multiplied with the chaotic carrier to drive the receiving system as the transmitting signal. Receiver and another adaptive controller to maintain the chaos synchronization of the receiving and dispatching system and restore the information signal.As the synchronization error has nothing to do with the information signal, the chaotic modulation communication of the large-scale and fast time-varying information signal is realized. Theoretical analysis and numerical simulation The results show that this method enhances the communication confidentiality of low-dimensional chaotic systems
