ECG Artifact Removal from EMG signals using Adaptive Filtering

[tsingh33]

I am a graduate student in the dept of Kinesiology at Pennsylvania State University, USA. I am trying to remove ECG artifacts from my EMG signals. I came across some papers that have used adaptive filtering to remove the ECG noise. I have listed some of these papers at the end of this post. I was wondering if someone on this group has a matlab function for an adaptive filter written that could remove ECG noise from EMG signals.

I will appreciate any help.

Thanks

Hello Tarkesh, It may help to widen your literature search to the general use of adaptive filters for EMG DSP as well. We used a Gram-Schmidt adaptive filter to remove stimulation artifact from EMG signals in real-time for FES applications. I do not have the code, but my colleague Dr. Hojun Yeom may be able to help you. You can contact him at: Hojun Yeom <hyeom@eulji.ac.kr>

Here is the paper reference as well:
Yeom HJ & Chang YH. Autogenic EMG-controlled functional electrical stimulation for ankle dorsiflexion control. J. Neurosci. Methods. 193: 118-125, 2010.

cheers,

Check out the user-contributed code at the Matlab Central file exchange , search for 'EMG' or 'adaptive filtering' or 'EMG [or ECG or EKG?] artifact' or whatever. Maybe you'll find something good there.
