A Statistical Approach to Signal Denoising Using VMD and CVM
Description of this data
This MATLAB code implements a data-driven signal denoising method published in Digital Signal Processing Journal and can be accessed from https://www.sciencedirect.com/science/article/pii/S1051200420302414?via%3Dihub.

Following are the details of the code
VMD_CVM_Main: This is the main file from where the whole code can be executed to perform denoising
Prop_VMD_CVM: Implements the the proposed denoising algorithm.
VMD.m: Performs variational mode decomposition of the noisy signal.
cvm.m: Implements the Cramer Von Mises statistic of the selected segment of the data
threshvspfa: Estimates threshold for a given Pfa using the rejected noise modes.
cdf_calc.m: matlab code to compute EDF
mse.m: Compute mean squared error for the denoised signal
snr.m: Compute signal to noise ratio for the denoised signal
sofar.mat, taichi.mat and ECGsig.mat contain the real world signals, of the same name, used in this study.
