Abstract :
Method for improving the signal-to-noise ratio of event related potentials (ERP) measurements is presented .The method is based on adaptive Fourier model. The Fourier model is based on the VSSLMS algorithm. A reduced number of single ERP trials being used for estimating the average response. The performance of the method is evaluated with simulations and real measurements of the ERP responses and compared to the ensemble averaging method
