Study on Frequency Resolution of Spectral Estimators using Non-linear Functions of the Covariance Matrix

摘要：

　　This paper studies the frequency resolution of two existing spectral estimators,where one is a generalization of the minimum variance spectral estimators (GMVSE) and the other is Pisarenkos non-linear spectral estimators (PNLSE).By this study,we show the uncovered relationship between the non-linear parameter and the frequency resolution for both the GMVSE and the PNLSE.The results bring out a clear guideline on choosing the parameters for both the GMVSE and the PNLSE to avoid missing any sinusoids.
