混沌的定义,从古至今一直在随着人们对它的了解在发生着变化。直到非线性动力学的发展到一定程度,通过对非线性动力学这门学科的不断研究,我们何以用非线性动力学的知识来定义混沌和计算出其准度。通过研究混沌信号发现其具有类似噪声的特点,信号没有周期性的重复,传输的频带非常宽并且是连续的,所以我们现在大多把混沌技术应用在保密通信和扩频通信中。从线性和非线性的角度混沌保密通信分为模拟混沌保密通信和数字混沌保密通信。数字混沌保密通信实际上就是把它的混沌
The definition of chaos has been changing as people understand it since ancient times. Until the development of nonlinear dynamics to a certain extent, through continuous study of the discipline of nonlinear dynamics, why do we use the knowledge of nonlinear dynamics to define the chaos and calculate its accuracy. By studying chaos signal, it is found that it has noise-like characteristics, the signal is not repeated periodically, and the transmission frequency band is very wide and continuous. Therefore, most of the chaotic techniques are now used in secure communication and spread spectrum communication. From the perspective of linearity and non-linearity, chaotic secure communication is divided into simulated chaotic secure communication and digital chaotic secure communication. Digital chaos secret communication is actually its chaos
