Position Estimation of Electroleortical Generators

Using subspace techniques we present simulated results investigating variations in ,the geometry of the sensor array for EEG measurements. We have shown that the perfimce of the subspace techniques degrades as the sources are brought closer to the array. This degrcidation can be counteracted by changing the curvature qf' the array. An optinaum array curvature exists which exhibits best detection performance for a given nngle of nrrival. We also present preliminary results applying subspace techniques to a sample of real EEG data.
