Signal Denoising Based on EMD

Although the empirical mode decomposition (EMD) is a new time-frequency analysis technique, it has a wide-ranging application in last decade. In this paper, we proposed a combined signal denoising method based on EMD and use the denoising method to recover the corrupted test signal. Three traditional denoising methods are combined with EMD to implement the signal denoising. The simulation validate the signal denoising method based on EMD is effective.
