Performance analysis of the UCA-ESPRIT algorithm for circular ring arrays
Cherian P. Mathews, M.D. Zoltowski · IEEE Transactions on Signal Processing · 1994
Statistical performance analysis of the UCA (uniform circular array)-ESPRIT algorithm is the subject of the present paper. The UCA-ESPRIT arrival angle estimates are shown to be asymptotically unbiased, and expressions for the asymptotic estimator variances have been obtained. Simulation results that verify the analysis are presented.>
