The previous ballistocardiogram (BCG) artifact removal
methods based on a reference layer used either a
customized electrode system or complicated experimental
procedures. In this work, we propose a practical and
efficient reference layer method and compare its
performance with the most popular method (optimal basis
sets (OBS)) on alpha-wave and sensory-evoked EEG
signals. By designing the reference layer as a reusable
cap, this method can be used directly with a standard
EEG cap and without any hard modification. The
comparison results showed that it has better performance
than the OBS in removing the BCG artifact.
