另外，通过局域波分析可把复杂的实测数据分解成有限个基本模式分量，从而简化信号分析过程，降低信号分析误差。
In addition, complicated tested data are decomposed into several intrinsic mode functions by this way, which low analyzing error, and predigest processing.
该文提出了一种新的非平稳信号的时变参数ARMA模型分析方法，用它分析数据需两个基本步骤：首先，用一种信号分解方法把信号分解成一些基本模式分量。
In this paper, a new method for time-varying ARM A model is introduced. It includes two procedures. First, using one method of signal decomposition, a signal is decomposed into some basic components;
