Two online implementations of the sample matrix inversion minimum variance distortionless response (SMI-MVDR) antenna array beamformer, based on recursive updating of the diagonal loading triangular matrix decomposition, are presented. The first proposed beamformer uses the Cholesky factorization recursive updating of the matrix whose dimension is increasing. The second beamformer uses the Householder transform (HT) recursive updating of the modified input data matrix. The proposed… CONTINUE READING
