摘要：

介绍S.L.Peng的基于瞬时频率和局部窄带信号的自适应分解方法，对两类局部窄带信号分解方法进行分析与研究。这种算法选取局部窄带信号作为基信号，通过构造奇异线性算子，从其零空间中提取局部窄带信号，从而实现信号的自适应分解,并通过与MP算法的比较，给出这两种算法的内在联系。

关键词: 瞬时频率, 局部窄带信号, 自适应分解

Abstract:

This paper introduces S.L.Peng’s adaptive signal decomposition based on instantaneous frequency and local narrow band signals, and then analyzes two types of local narrow band signal decomposition method. This algorithm selects local narrow band signals as the base signal, and extracts local narrow band signals from the null space of a singular local linear operator, so as to achieve the adaptive signal decomposition. By comparing with the Matching Pursuit (MP) method, it gives their internal relations.

Key words: instantaneous frequency, local narrow band signal, adaptive signal decomposition
