De-noising of Electrocardiogram (ECG) with Adaptive Filter Using MATLAB

Abstract

Problem associated with biomedical signal like ECG is to extract noise cause by high frequency interference, electromagnetic fields, power line interference and body movement. It is difficult to apply filters with fixed coefficients to reduce random noises. Adaptive filter technique is required to overcome this problem. This paper presents an innovative technique for estimation of ECG waves using Adaptive Noise Cancellation (ANC) algorithm, widrow-hoff LMS algorithm. Comparisons are made for original signal to noisy. Simulations are done for random noise pattern in mat lab.
