Efficient Levinson and Schur-type algorithms for block near-to-Toeplitz systems of equationsEfficient Levinson and Schur-type algorithms for block near-to-Toeplitz systems of equations Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-081994enIn this paper new efficient Levinson- and Schur-type algorithms are derived for block near-to-Toeplitz systems of equations. In contrast to previously derived algorithms, the block near-to-Toeplitz property is exploited on a scalar level leading to Levinson- and Schur-type algorithms based on scalar instead of matrix operations. As a consequence, the highly parallel Schur-type algorithm can be implemented in a straightforward way on a linear array processor, consisting of scalar operators locally connected.http://creativecommons.org/licenses/by/4.0/Signal Processing 335241–255 Liavas Athanasios Λιαβας Αθανασιος Theodoridis, Spyros Elsevier Levinson-type algorithms
