... IN THE MEAN OF THE SPLIT SR-RLS We start by proving that the convergence of the split SR-RLS algorithm is determined by the cross correlation matr ix be- tween the update direction l (k) and the ... algorithm. To see the benefits of the split SR-RLS scheme, we should compare the proposed scheme with the original SR-RLS ini- tialization. When SR-RLS is applied for the PT...
