Segmented matched filtering of single event related evoked potentials

A fast segmentation-based matched filtering (MF) technique of single trial evoked potentials (EP's) is presented. MF improves the signal-to-noise ratio of single EP's, reducing the number of repetitions necessary to obtain high quality signals by an order of magnitude. A computer simulation and analysis of experimental data of movement related potentials and cognitive event related potentials demonstrate the superior capabilities of MF compared to traditional ensemble averaging.<
