一个新的开关超混沌及其DSP实现

A New Switched Hyperchaos and Its DSP Realization

为了提高混沌的复杂性,提出了一个开关超混沌系统。该系统包含2个不同的超混沌子系统,其结构和参数在其自身变量的控制下不断地在这两个子系统之间变化,其行为比传统的超混沌更具复杂性。为产生数字超混沌信号,基于DSP芯片研究了该开关超混沌系统的数字化实现问题,在实验中获得了数字化的混沌序列。该系统及其数字化方法可应用于通信、信息加密和计算机等领域之中。

In order to enhance complexity of chaos,a new switched hyperchaotic system composed of two hyperchaotic subsystems is proposed,and its structure and parameters could automatically change between these two subsystems under the control of its variables.The proposed system is more complex than the traditional system in behaviors.Based on DSP chip for generating digital hyperchaotic signal,the system digitalization is studied and implemented,and the digital chaotic signal is successfully obtained in the experiment.The proposed system could be used in the domains of communication,information encryption,computer,and so on.
