| 摘 要： | 提出了用离散混沌系统驱动连续混沌系统导致其同步的方法，以逻辑映象、Henon映象、Lorenz系统为例，数值地研究了这种混沌同步方法.模拟结果表明，当驱动信号的强度足够大时，可使两个连续混沌系统达到完全同步，且输出信号具有类似于白噪声的宽谱特性.同时研究了用该混沌同步方法实现保密通信的可能性.

| Abstract: | In this paper, the method of synchronizing chaos by driving of discrete chaotic system in continuous chaotic systems is proposed. The logistic map, Henon map and the system of Lorenz are taken as three typical examples. The simulation results show that two continuous chaotic systems can be synchronized completely when the strength of the driving signal is large enough and the spectrum of the output signal is similar to the spectrum of white noise. At the sametime, we have studied the possibility of secrete communication based on the method proposed in this paper. |
