Abstract :
Localization of multiple-parameter sources is considered in this paper. Specifically, the problem of localizing EEG polarized sources is addressed. Expressions are presented for the variance of the source parameter estimates for the MUSIC estimator. The expressions are presented for both finite sample effects and the model perturbations effects. A comparative study of the performance is presented when the dipole orientation is known and unknown
