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
