A vectorized systolic array for parallel weight extraction of block RLS

摘要

AbstractA new vectorized systolic array for extracting weight coefficients in block RLS is proposed. Our array is based on a generalization of the inverse factorization method of Pan and Plemmons and the array for computing residual vectors in block RLS using the Householder transformation of Liuet al.the new array is obtained by first generalizing the inverse factorizations for the block case and then deriving a formula for updating the tap coefficients without matrix operations.
