Title

Iterative Algorithm For Design Of Vector Quantisation Codebooks In Nonorthogonal Domains

Abstract

An iterative algorithm for codebook accuracy enhancement, applicable to waveform and linear prediction (LP) model-based vector quantization in nonorthogonal domains, was presented. Two equivalent nonorthogonal representations of the LP coefficients, log area ratios (LAR) and line spectral pairs (LSP) were used and the vector formed in each domain of representation of the LP coefficients was split into two subvectors. The results exhibited the improvement in signal reconstruction quality without increasing the bit rate, when the proposed algorithm was applied to speech signals.
