Second order statistics based blind source separation for artifact correction of short ERP epochs [PDF]

open access: yes, 2003
ERP is commonly obtained by averaging over segmented EEC epochs. In case artifacts are present in the raw EEC measurement, pre-processing is required to prevent the averaged ERP waveform being interfered by artifacts. The simplest pre-processing approach
