Abstract
It is postulated that by proper selection of the stimulus frequency in SSVEP BCI systems and comb filtering of the EEG signal prior to performing the DFT, substantial increase of the SSVEP signal-to-noise ratio can be achieved. This enhancement may contribute to the speed and accuracy increase of brain-computer interfaces. Experimental results are presented to confirm the comb filter usefulness.
