Analysis of structured excitation codebooks used in CELP speech compression algorithms

This paper presents an analysis of different suboptimal codebook excitation schemes used in code-excited linear prediction (CELP) speech compression algorithms. The problem of low rate, shape-gain vector quantization is formulated. Analyses of pulse codebooks, circularly recursive codebooks, algebra...

Zusammenfassung:	This paper presents an analysis of different suboptimal codebook excitation schemes used in code-excited linear prediction (CELP) speech compression algorithms. The problem of low rate, shape-gain vector quantization is formulated. Analyses of pulse codebooks, circularly recursive codebooks, algebraic codebooks, and vector sum codebooks are presented.
