It included Lempel-Ziv complexity and fractal dimensionality. When extracted Lempel-Ziv complexity measure, we presented a method of restructuring signals, which could improve collection degree of within and separation degree of between classification.

• 在Lempel-Ziv复杂度的提取中,本文提出了一种有效的序列重构方法,以此来提高特征的类内集群程度和类间分离程度。
