Comparative studies of MUSIC and MVDR location estimators for model perturbations

A comparative study of the statistical performance of the MUSIC and minimum variance distortionless response (MVDR) direction of arrival (DOA) estimators is presented. Their relative performance due to given modeling errors is studied. In particular, we study the sensitivity of the estimators to mod...

Summary:A comparative study of the statistical performance of the MUSIC and minimum variance distortionless response (MVDR) direction of arrival (DOA) estimators is presented. Their relative performance due to given modeling errors is studied. In particular, we study the sensitivity of the estimators to modeling errors in the signal and noise structures.
