Abstract : A cascaded synchronized system includes a nonlinear transmitter, a nonlinear cascaded receiver, a phase-detector/controller coupled to the receiver, and a signal generator also coupled to the receiver. The transmitter is responsive to an externally generated transmitter forcing signal for producing and transmitting a chaotic communications signal containing phase information. The cascaded receiver is responsive to a receiver forcing signal and to the chaotic communications signal for producing a chaotic receiver output signal containing phase information. The phase-detector/controller is responsive to the chaotic communications signal and to the receiver output signal for producing a correction signal. The signal generator is responsive to the correction signal for producing the receiver forcing signal in phase with and having the same frequency as the transmitter forcing signal.
