In order to improve the transmission and safety performance of the single-stage chaotic system, such as chaotic masking, chaotic shift keying, and chaotic modulation, we present a new three-stage chaotic communication system. The chaotic systems in both the transmitter and the receiver end are consisted of the unified chaotic system, which has only one parameter need to be set. By adjusting the parameters in the linear system and the interference system, we can produce tens of different kinds of transmission signals, which make it more difficult for the illegal receiver to decode the encrypt signal. The simulation results show that the system will realize synchronization quickly, and the information signal can be recovered successfully under different parameters of the unified chaotic system.
