Key result
The proposed Parallel EMD Adaptive Filter (PEAF) algorithm yielded the best Signal-to-Noise Ratio improvement for denoising ECG signals corrupted by four common types of noise compared to other methods.
Why the study?
ECG signals are essential for diagnosing cardiac diseases but are frequently contaminated by various noises including baseline wander, power line interference, electrode motion, and muscle artifacts.

May aid ECG denoising research; extends adaptive filtering methods but leaves clinical validation open.
Does a Parallel EMD adaptive filter structure improve signal-to-noise ratio in ECG signals corrupted by various artifacts?
A novel Parallel EMD adaptive filter structure effectively denoises ECG signals corrupted by multiple common artifacts, improving signal quality for cardiac diagnosis.
Dai et al. (2021) studied ECG signal denoising. Parallel EMD Adaptive Filter (PEAF) vs. Other denoising algorithms (SDAF, PDAF, SEAF, and prior state-of-the-art methods) was evaluated on Signal-to-Noise Ratio improvement (SNRimp). The proposed Parallel EMD Adaptive Filter (PEAF) algorithm yielded the best Signal-to-Noise Ratio improvement for denoising ECG signals corrupted by four common types of noise compared to other methods.
