摘要
本文讨论了蔡氏混饨同步通信系统的主要性质和局限性,提出了一种多级混沌安全通信系统,证明了该系统对传输信号可以完全重建,在有效带宽、失真特性及安全特性方面获得了改善.文中给出了利用该系统进行语音数据和静止图像数据传输的实例.
Chua's chaotic synchronized system and its main properties are investigated and a multistage chaotic synchronized system for secure communication is proposed. It is shown that the message signal hidden in chaotic drier of the system can be perfectly reconstructed, and the bandwidth, the characteristic of distortion, and the level of security are improved. Examples of speech and still image communication are presented by using the system. level of security are improved.Examples of speech and still image communication are presented by using the system.
