提出了一种利用混沌载波进行数字通信的方法 ,该方法通过调制周期激励混沌系统中周期激励项的相位来传输数字信号 ,并在接收端利用由可同步的串联结构的混沌系统组成的最佳接收机进行相干解调 .所提方法能传输二进制信号 ,也可推广到传输多进制信号的情况 .最后进行了数值仿真 ,结果说明了所提方法的有效性 . 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.
