A ROBUST DEMODULATION APPROACH TO COMMUNICATIONS USING CHAOTIC SIGNALS

Abstract

In this Letter, a new demodulation approach to communication using chaotic signals is presented. Information signal is modulated by applying it as an input to a chaotic system. At the receiver, a synchronous subsystem is constructed for estimates on the states of the chaotic system. The key innovation in our communication system is a new robust filter that recovers the information signal from the scalar transmitted signal.
