Title: LSF Parameter Vector Quantization CodeBook Design Based On Genetic k-Means Algorithm
Abstract: A Line Spectrum Frequency(LSF) parameter codebook design method based on genetic k-means algorithm is introduced.By using k-means algorithm as a novel genetic crossover operator and the method of replacing the codebook's codes by the training vectors randomly as the genetic mutation operator,the experimental result shows that it is effective and the code book generated by this method is better than the one generated by the traditional splitting LBG method with the same codebook size.
