Multi-Order Intermittent Chaotic Synchronization of Closed Phase Locked Loop

For the model of a Closed Phase Locked Loop (CPLL) communication System consists of both the transmission and receiver ends. This model is considered to be in a multi-order intermittent chaotic state. The chaotic signals are then synchronized along side with our system. This chaotic synchronization will be demonstrated and furthermore, a modulation will be formed to examine the system if it will perfectly reconstruct or not. Finally we will demonstrate the synchronization conditions of the system.

基于系统重构的混沌保密通信系统的信息检取

在仅能得到混沌发送信号并能获得足够多未加通信信息的发送信号的情况下,分别对通信信息调制入和未调制入混沌发送系统的两类混沌保密通信系统进行研究。首先用发送信号进行系统重构,然后用重构系统及以未加通信信息的重构点为领域对加有通信信息的发送信号进行一步预测。文中推导出发送信号、预测信号之差与通信信息之间的关系,并从发送信号中直接提取通信信号。以Lorenz系统为例说明本文结论。
