【摘要】 针对自适应码本搜索中的多级基音预测算法计算量大的缺点,本文提出了两个递推算法。采用这两个算法,可以大大的降低多级基音预测的计算量,而对多级基音预测算法本身数值没有任何的改变。更多还原

【Abstract】 Two recursive algorithms are presented in this paper,which is suitable for reducing the heavy computation complexity of multi-tap pitch predictor algorithm in adaptive codebook searching.Using these recursive algorithms, we can make multi-tap pitch predictor algorithm to have less computation complexity.No numerical value change is made on multi-tap pitch predictor algorithm when recursive algorithms are used.更多还原
