Abstract :
Introduces a normalized version of the least squares order-recursive lattice (LSORL) smoother, say the normalized LSORL smoother. The normalized LSORL smoother has excellent round-off noise properties and inherits all the other advantages of the normalized LSORL as well. Simulation results show that the normalized LSORL smoother outperforms the existing LSORL smoother when finite-precision arithmetic is used
