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 improve the complexity of chaos, a hyperchaotic switch system is proposed. The system consists of two different hyperchaotic subsystems whose structures and parameters are constantly changing between the two subsystems under the control of their own variables. Their behavior is more complex than the traditional hyperchaotic subsystems. In order to generate digital hyperchaotic signals, the digital realization of the hyperchaotic system is studied based on DSP chip. The digital chaotic sequence is obtained in the experiment. The system and its digitization method can be applied in the fields of communications, information encryption and computers.
