A Study on Optimum Weight Value and Cost MUSIC Algorithm of Array Steering Vector

This paper estimate a desired signal using adaptive array antenna in wirless communication system. Position of target is to estimate for desired direction of arrival among incident signals with receiver system. We use an adaptive array antenna. In order to obtain an optimum weight value, we study direction of arrival estimation algorithm with cost MUSIC algorithm. Through simulation, we show that compare cost MUSIC algorithm with general algorithm. In this paper, Direction of arrival estimation improved more proposed algorithm than general algorithm.
