Low Complexity Lpc Quantization Using The Structured Vector Quantizer
Mei Yong, V. M. Eyuboglu · 2005
This paper describes the findings of a recent study on quantization of the LPC parameters, represented as the arcsine of the reflection coefficients, using the structured Vector Quantizer (SVQ). Our results show that the SVQ can reduce the bit-rate by about 12 percent, compared to a conventional scalar quantizer. The SVQ also achieves a better performance than a split-VQ at a much lower implementation complexity.
