Abstract

An adaptive antenna array is considered that simultaneously suppresses wide-band spatial interference and receives a wideband useful signal. An algorithm for the formation of weight coefficients in the basis of power vectors is proposed. Accurate analytical expressions for weight vectors are obtained. It is shown that the proposed method works for the case of a short sample of the input process. The mechanism of regularization of weight vectors is proposed. The estimation and comparison of the computational complexity of the proposed algorithm and the method of direct inversion of the matrix is made. The proposed method of power vectors has less computational complexity. The results of modeling are shown, which show the high efficiency of the proposed method.
