Abstract
An adaptive beamforming method for an antenna array is provided in which an array output is calculated based on a weight vector , which is determined from an eigenvector corresponding to a maximum eigenvalue&lgr; of a generalized eigenvalue problem consisting of autocovariance matrixes and of received signal vectors and , respectively. The present invention dramatically decreases the total computation requirements by omitting complex matrix operations from the weight vector calculation, thereby making it possible to reduce the weight vector calculation time so as to form the beam pattern for the array antenna system in real time.
