| 摘 要： | 研究了四阶细胞神经网络超混沌系统同步方法，分析了系统存在参数失配和信道噪声时的同步性能，提出了一种基于细胞神经网络超混沌同步系统的扩展频谱保密通信设计方法。提出的扩频保密通信方法不仅只需传递一个标量信号，而且由于采用了超混沌系统，所设计的扩频通信系统具有更高的保密性。

| Abstract: | In this paper,we study the synchronization approach for hyperchaos system of 4th order cellular neural network,analyze its performance in the presence of parameter mismatch and channel noise,and propose a design method for a spread spectrum secure communication system based on hyperchaos of cellular neural network.The proposed method only needs to transfer a scalar signal and provides higher security due to the use of hyperchaos. |
