An improved method for signal de-noising based on multi-level local mean decomposition
The product functions (PFs) extracted by local mean decomposition (LMD) of the noisy signal contain obvious energy-concentrated pulses. As a result, the conventional amplitude threshold filtering used in wavelet transform (WT)-based and empirical mode decomposition (EMD)-based de-noising methods is...
