waveform interpolation 中文意思是什麼
-
In order to obtain a high - quality speech codec, the phase information of speech should be included in codec. in this thesis, a method for quantizing the phase of sew ( slowly evolving waveform ) and reconstructing sew ’ s phase with cubic polynomial interpolation is given based on the perceptual weighting analysis - by - synthesis ( a - b - s ) vector quantizer for the phase spectrum in wi coder
本文基於感覺加權相位譜分析合成（ abs - analysis - by - synthesis ）矢量量化方法，給出了一種wi編碼器中慢漸變波形（ sew - slowlyevolvingwaveform ）的相位信息量化及合成端相位的三次多項式插值重建方法。 -
Waveform interpolation speech coding is one of the most potential low - rate speech coding algorithms in recent years. with high performance, wi technique has been widely concerned
