The new algorithm has three characters : first is that the new algorithm is on the basis of super frame which include 3 continuous simple frames in melp algorithm, the algorithm deal with parameters of a super frame by the mode of the super frame. secondly, two algorithms are introduced for improving vector quantization quality of line spectral frequency ( lsf ) parameter. one is swithed - adaptive inter - frame vector prediction ( sivp ), which can get rid of the correlation between neighboring frames effectively, the other is joint codebook optimization for multi stage vector quantization ( jco - msvq ), which can improve performance of codebook
第二是在製作線譜對參數( lsf )矢量量化碼本時,引入了目前提高lsf碼本性能的兩個方法:在利用重點幀對非重點幀作預測時,借鑒自適應幀間矢量量化( sivp )去除相關性演算法的優點,提出了以固定矩陣去除相關性的方法,有效的控制了預測后殘差的動態范圍,提高了對殘差矢量量化的精度;採用聯合碼本優化多級矢量量化演算法( jco - msvq ) ,改良多級矢量量化碼本的性能。
