    ACELP语音编码中代数码书的快速搜索算法

    A Fast Searching Method of Algebraic Codebook in ACELP Speech Coding

      摘要
    • 摘要: 为降低ACELP语音编码中代数码书搜索的复杂度,提出了一种基于代数多子码书结构的多路径快速搜索算法.实验结果表明,在不降低编码质量的条件下,这种搜索算法的复杂度仅为全搜索算法的1/128.

       

      Abstract: To reduce the the complexity of algebraic codebook searching,a fast multi-path searching algorithm based on algebra sub-codebook is presented.Experimental results show that the complexity of the proposed method is 1 of 128 of full searching method while the quality of speech coder is not affected.
