Impinging Signal Estimation of Minimum Variance Method Using Updating Weight
This paper study on estimation signals of the wireless channels. We propose new algorithm in order to esitmation desired singal correctly to remove noise signal and interference supression. Proposed algorithm is to combine minimum variance method with updating weight value. Minimum varinace method, form constrained 1, is direction-of-arrival estimation algorithm. We obtain updating weight of minimizing error signal using lagarge multiplier. We search the signal direction taht we want to estimate substituting updating weight in minimum variance method. Through simulation, we compare proposed algorithm using both minimum varinace method and updating weight with the traditional MUSIC algorithm. Numerical results demonstrate the superior performacne of the proposed algorithm relative to the gerneral MUSIC algorithm.
