A Novel Approach for the Reduction of 50Hz Noise in Electrocardiogram Using Variational Mode Decomposition

Conclusion: This paper provides a novel method in the area of denoising Biosignals. Two techniques are proposed for denoising such as direct subtraction and indirect subtraction techniques. A comparative study is performed to study the performance of the proposed method. The parameters used for comparison are MSE, SNR, PRD and PSNR. Indirect subtraction technique outperforms the direct subtraction method. An improved SNR value and minimized MSE indicates the performance of denoising method. Thus VMD based subtraction techniques give better denoised signals even though the decomposition process takes time.
