Abstract

A pole trajectory analysis is presented for high-order autoregressive processes of movement-related potentials recorded from the human scalp. The aim is to obtain a geometrical pattern related to spectral analysis of these potentials. It is shown that this pattern can be used for matching data from different groups of subjects or recognizing electroencephalographic signals contaminated by artifacts. Poles are estimated using simultaneous determination of the polynomial roots algorithm and other factorization schemes. The pole trajectory analysis is performed using a time window of 500 ms moving through the recording for 2.5-ms steps. Results show that most of the pole trajectories are fitted by a cardioid.
