摘要
从信号处理的角度介绍了混沌信号的特征量李雅普诺夫指数、分形维数和熵的概念 ,并给出了区分确定性信号、随机信号和混沌信号的判断标准 .文中还提供了语音信号、心电信号的应用实例 。
In terms of signal processing, the paper intrduces characteristics of chaotic signal-Lyaponov exponent, fractal dimension and entropy. It also gives a criterion to distinct certain signal?stochastic signal and chaotic signal. And it shows the correctness of the criterion by giving examples.
