摘要
提出由一阶时延微分方程描述的无限维混沌系统,在结构上易于实现。本文将有用信号直接输入该系统以实现保密通信,理论推导和实验结果均表明在经历很短的过渡时间后,接收端和发射端能很快同步。本文的模型在很大参数范围内都能产生混沌,因此具有良好的保密性。
A chaotic masking system is proposed based on synchronization of chaotic models described by onevariable differencedifferent equation. Signals to be transmitted are injected into the model. The proposed system has a large chaotic regime and it is easy to be implemented.
