A method of digital communication using chaos carrier is proposed. The method transmits the digital signal by modulating the phase of the periodic excitation in the chaotic system, and uses the chaotic system composed of synchronizable serial structures at the receiving end to transmit the digital signal. The receiver performs coherent demodulation.The proposed method can transmit binary signals, but also can be extended to the case of transmitting multi-band signals.Finally, the numerical simulation is carried out and the results show the effectiveness of the proposed method.
