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.
This paper presents the scheme of digital communication using a chaotic carrier.In the transmitter
the bits are mapped to sample functions of chaotic signals emanated from one or more chaotic attractors by modulating phase of excitation term of driven Chua's circuit.The bits are demodulated by the optimal demodulator that consists of synchronizable chaotic circuits in the correlation receiver.The proposed scheme can be used for transmitting binary signal and be extended for M-ary signal.Finally
the numerical simulation results demonstrate the proposed scheme effectiveness.
