| Abstract: | Higher-order spectral (HOS) technology is applied to the nonlinear detectionand bispectral analysis of EEG signals based on personal computer system. Non-Gaussian ARmodel is proposed to the modelling of EEG signals. The model parameters are used for thenonlinear detection and the parametric bispectral estimation of the EEG signals. The bispectraldiscrete implementation and the analysis system are also discussed. The effect of the back-ground noise is effectively rejected due to the bispectral technology. The results presented inthis paper show that the polyspectral technique proposes a new way for analyzing the EEG andother medical signals. |
