| 摘 要： | 矢量量化的计算量主要在于搜索最近的码字，这也是矢量量化实用化的障碍。作者在该文中提出了一种不增加量化噪声快速编码算人实验结果表明，所提出的快速编码算法相对于穷尽搜索算法只需增加较小存储量，就将使小算时间可大大降低。

| Abstract: | The computation of vector quantization which is mainly depending on the search of the nearest codeword is the main barrier of practicalization of vector quantization.In this paper,a fast encoding algorithm that does not enhance quantization noise is introduced.Fxperimental results show that this algorithm can reduce the time of encoding greatly at the cost of a little of extra storge. |
