In this note we propose a new chaotic modulation schema with output feedback. It is shown that the receiver can synchronize with the transmitter with any desired rate. Moreover, this approach can be applied to a large class of chaotic systems and provides higher security against an intruder. The robustness of our scheme with respect to noise is illustrated and compared, to the symmetric chaos shift keying method.
