VERFAHREN ZUR QUANTISIERUNG DES VERSTÄRKUNGSFAKTORS FÜR DIE LINEAR-PRÄDIKTIVE SPRACHKODIERUNG MITTELS ANALYSE-DURCH-SYNTHESE |
摘要 |
A gain quantization method, in analysis-by-synthesis linear predictive speech coding, includes these steps: determine a first gain for an optimal excitation vector from a first code book; quantize the first gain; determine an optimal second gain for an optimal excitation vector from a second code book; determine a linear prediction of the logarithm of the second gain from the quantized first gain; and quantize the difference between the logarithm of the second gain and the linear prediction. |
