Abstract
We consider the problem of detecting visual evoked potentials (VEPs). A matched subspace filter (MSF) is applied to the detection of the VEP and is demonstrated to perform better than a number of other evoked potential (EP) detectors. Unlike single-harmonic detectors, the MSF detector is suitable for detecting multi-harmonic VEPs. Moreover, the MSF is optimal in the uniformly most powerful (UMP) sense for multi-harmonic signals with unknown noise variance
