COVARIANCE MATRIX FOR ADAPTIVE BEAMFORMING

摘要

A method and apparatus for generating a covariance matrix during adaptive beamforming of a multi-beam antenna. The method uses an upper right triangle of the covariance and time sharing of complex conjugate multipliers to efficiently compute the covariance matrix. In addition, a variable number of beams may be selected in the covariance matrix according to an operating environment of the multi-beam antenna.
