Frequency recognition based on canonical correlation analysis for SSVEP-based BCIs

IEEE Trans Biomed Eng. 2007 Jun;54(6 Pt 2):1172-6. doi: 10.1109/tbme.2006.889197.


Canonical correlation analysis (CCA) is applied to analyze the frequency components of steady-state visual evoked potentials (SSVEP) in electroencephalogram (EEG). The essence of this method is to extract a narrowband frequency component of SSVEP in EEG. A recognition approach is proposed based on the extracted frequency features for an SSVEP-based brain computer interface (BCI). Recognition Results of the approach were higher than those using a widely used FFT (fast Fourier transform)-based spectrum estimation method.
