| 摘 要： | 在格型矢量量化中，用格点作为量化矢量，构成码书。为了存储或传输量化输出，必须对格点进行标号。我们在数据压缩课题研究中，对塔式网格矢量量化中格点的标号进行了探索，给出了常用的几种网络诸如ZL、DL、E8、A16等格点的标号算法。

| Abstract: | In latt1ce vector quantization, the codebook is made up Of lattice points as qantization vectors. It is essential to give an index to a lattice point, so that the output of quantizer can be stored or transmitted. In our study of data compression, an entire research is given to the problem of the index of lattice points in pyramidal lattice vector quantization,and index algorithms are presented to index the Iattce points of some usually-used lattices,such as ZL, DL, E8 and A16so on. |
