Key result
FAST ICA demonstrated a higher performance index (0.357 at 10dB noise) compared to JADE ICA (0.294) for denoising ECG signals.
Why the study?
Artifacts like persistent and burst noises make ECG signals difficult to interpret and analyze, requiring denoising solutions such as independent component analysis.
FAST ICA is more effective than JADE ICA for denoising ECG signals, yielding a higher Performance Index despite higher memory usage.

FAST ICA may enhance ECG denoising in engineering contexts; leaves open clinical utility pending validation.
Electrocardiograph signal is effective tool in diagnosis of cardiac related diseases and plays an important role in biomedical research. To diagnose the cardiac disease, the signal must be recorded properly. The addition of artifacts like Persistent noises, Burst noises and their types play an important in making it difficult to interpret and analyses the electrocardiograph signal. A Blind source separation (BSS) related technique named Independent Component Analysis (ICA) is the right solution for it. In this paper, different ICA Algorithms like JADE, FAST are used to de-noise the ECG signal from the artifacts and a comparison between both is shown which is done on the basis Performance Index (PI) using a dsp ICALAB toolbox in MATLAB.
