In this paper, an inverse system approach for communications using chaotic signals is presented. In this approach, the transmitter contains a chaotic oscillator with an input that is modulated by the information signal. The receiver is a linear asymptotic approximation to the inverse system and contains an integral feedback to cope with nonlinearities. Some effects of transmission noise on the demodulation procedure are discussed. Numerical simulations on the Chua's circuit are provided to illustrate our findings.
