Abstract—This paper studies the estimation of the desired signal received on the array antenna in the correlated wireless communication environment. The direction of arrival signal applies updated weight to the Bartlett method for estimation the desired signals. In this paper, the proposed method applies the optimal weight vector to the output energy of the Bartlett method. The optimal weight of the Bartlett method estimates a desired signal to obtain the optimal weight of the covariance matrix. The optimal weight of the covariance matrix isestimated correctly the position to remove the interference and the noise signal andminimizing for the estimation error of the desired signal by applyingminimum variance method to Bartlett method. Optimum weight of minimum variance method is obtained by optimal covariance matrix using cost function to estimate a desired signal. In the minimum variance method, a covariance matrix value is obtained using a cost function to estimate a desired signal, and an optimum weight value is obtained. Through simulation, we compare proposed Bartlett method and the classical the method. As a results simulation, the performance of the proposed method is superior to relative to the classical the method.
