Abstract
A computationally efficient implementation of the Levinson algorithm in two steps that dramatically reduces the computational coal is presented. The a lgorithm uses the generalised Levinson recursion for block matrices as a fi rst step, and the Gohberg-Semencul formula as a second step, saving similar to 75% in terms of the computational cost for a typical two-channel deconv olution problem.
