Abstract: In order to synchronise transmitter and receiver in chaotic communication, an identical chaotic receiver of transmitter should be applied. It is impossible to construct a replica of the transmitter when there exist uncertainties in transmitter end and transmission line. In this paper a new kind of receiver, called robust receiver, is proposed for robust chaotic communication. The receiver design is based on proportional-plus-Integral (PI) and Proportional (P) forms high gain observers, the chaotic receiver can be different from the transmitter. We prove that the communication single error can be arbitrary small if we select a proper observer gain in the receiver. A chaotic systems is used to illustrate the robust chaotic communication.
