摘　　要：提出基于时空混沌序列的保密通信方法,提出了一种用时空混沌模型产生扩频地址码的方法,讨论了驱动序列的选择方法与原则,分析了其耦合同步特性,给出了一种具体的通信系统模型。实验结果表明:此模型具有较高的保密特性和较强的同步能力,并且易于实现。另外,只用很少的几路离散混沌序列作为同步序列就可传输多路信息,有效地提高了系统的信息传输效率。The method of secure communication based on Spatiotemporal chaotic sequence is proposed, a method using spatiotemporal chaotic model to create spread - spectrum sequence is presented, and the problem of choosing a driving system synchronous sequence is discussed. Based on the above, a model of CDMA communication system is given. The result illustrates that the system possesses high security and stronger synchronizing ability and is easy to realize. In addition, by using only one or two discrete - line synchronizing chaotic sequences the system can be driven to work in multi-channel communications, thus the communication efficiency is enhanced significantly.
