101 A Study on Position Target Using Direction of Arrival Estimation Algorithm in Wireless Communication System

In this paper, we are proposed algorithm of target position in mobile wireless channel that has estimated the direction of arrival. The proposed algorithm applied the spatial average method in a MUSIC algorithm. The diagonal matrix of the spatial average method was changed to inverse the matrix and to obtain a new signal correlation matrix. The existing algorithm was analyzed and compared by applying a proposed signal correlation matrix to estimate the direction of arrival in a MUSIC algorithm. The experiment resulted in a proposed algorithm with a linear predicted algorithm and Min-norm algorithm resolution at more than 5o. It was improved more than 2o in a MUSIC algorithm.
