Abstract :
A new vectorized rhombic systolic array for computing tap coefficients in the block recursive least squares (RLS) method is proposed. The array is based on the inverse factorization method of Pan and Plemmons (1989) and on the triangular array for computing residual vectors in block RLS using the Householder transformation of Liu et al. (1990). The new array is obtained by generalizing the inverse factorizations for the block case and then examining the relation between the a priori error vector and the a posteriori error vector to get rid of the matrix operations
