Abstract

Various methods have been proposed for adapting the coefficients od digital lattice filters used in linear predictive speech coding systems.
The most common of these is the stage-by-stage algorithm based on the least mean square (LMS)) METHOD.
In this paper a new sequential adaptive algorithm referred to as "end-point" method is introduced. A comparison study between the stage-by-stage and the "end-point" has been carried out by computer simulation. The preliminary results showed that the "end-point" provides higher convergence rate and less misadjustment in mean-square error over the stage-by-stage method.
