| 摘 要： | 提出了一种新的通过双参数非线性反馈函数来实现一般logistic映射的驱动响应系统的同步方法，该方法能够避免现有的线性反馈和非线性反馈中出现的弱同步现象，并且在不同的参数空间下同样可以保证同步，对一般的logisdc映射普遍适用。本文重点论述了在2个参数控科下的非线性反馈的同步原理及性能，通过数值仿真验证了该算法的有效性和对噪声的顽健性，并说明了该算法在保密通信中的应用。

| Abstract: | A new approach, which uses a nonlinear feedback function with two parameters to realize synchronization in driver-response systems in general logistic map, is proposed in this article. This algorithm can avoid weak synchronization in linear feedback and general nonlinear feedback functions. Driving and response systems can preserve synchronization even with different parameters. We discuss the principle and performance of this nonlinear function in details, and validate the efficiency and robustnenss in the noisy environment. Finally, we show this approach is very useful in the secret communication.2002-03-05 |
