A new beamforming method for direct sequence code division multiple access systems is presented. This method is based on Rayleigh quotient of the despread signal's covariance matrix. Two eigenvector analysis algorithms, simple steepest descend algorithm and an algorithm presented by Luo, are used to obtain the new beamforming method. It is shown that both algorithms result in the same updating equation for the weight vector. The proposed method needs only 2N+1 complex multiplications and 2N-1… CONTINUE READING
