Directional of arrival (DOA) estimation technology play an important role in enhancing the performance of adaptive arrays for mobile wireless communications. A number of DOA estimation algorithms have been developed during the year. In this paper we present the performance analysis and comparison for Capon and MUSIC DOA estimation algorithms with a uniform circular array. Our focuses were to unveil the relationship between the mean square estimation error (MSE) and system resolution with phase mismatch. Monte Carlo simulation study results have been presented to illustrate the dependence of MSE with the quality of array calibration. The dependence of MSAE on array element number was also studied.
