摘要：

A wavelet-based method is introduced for removing structured noise (e.g., impulsive spikes or unwanted harmonic components) from data. For this type of noise, the time- and frequency-localization capabilities of wavelets provide better noise detection and less signal distortion than direct filtering of data, The procedure is applied to time-series data with impulsive noise and transfer-function data with multipath interference.
