A multi-stage levinson-durbin algorithm

Abstract

This paper proposes an adaptive multi-stage Levinson-Durbin algorithm, which is more numerically robust than the conventional Levinson-Durbin algorithm for input signals with high spectral dynamics such as speech or audio signals. At the same time, the proposed algorithm preserves the computational efficiency of the Levinson-Durbin algorithm. It can be therefore suitable to be used in practical linear prediction coding systems as a replacement of the Levinson-Durbin algorithm for better coding performance.
