Chun, J. ; Kailath, T.
Abstract :
We present an efficient and numerically stable implementation of a class of adaptive beamforming algorithms. Our method is based on a variant of the URV factorization, and is particularly useful when the effective rank of the data matrix is smaller than the number of antenna elements, which is usually the case when the number of signal sources is smaller than the number of antenna elements in a high SNR environment.
