A Fast Searching Method of Algebraic Codebook in ACELP Speech Coding
Zexin Liu · Journal of Beijing University of Technology · 2007
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.
