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. 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.
