The first part of this thesis is basic on the generalized Hamming weights of linear codes over rings and arranged as follows: In section one, we first introduced the definition of generalized Hamming weights and weight hierarchy over binary field GF (2) and its extension to nonlinear codes over GF (2) and linear codes over rings.

本文的第一部分就是围绕环上线性码的广义Hamming重量这个课题展开的，主要内容如下：第一节，首先介绍了GF(2)上线性码的广义Hamming重量和重量分级的概念，以及这些概念是如何被推广至非线性码及环上的线性码上的。

From the sequence correlation requiring of Turbo codes coding and decoding, correlation of sequence is proposed as a criterion to design interleaver. a good interleave scheme called clinodiagonal interleaver is obtained.

研究了高码率Turbo码的两种构成方案，给出删除法交织器的设计方法，通过对两种构成方案的性能和译码复杂度比较，得到了删除法构成高码率Turbo码能在译码复杂度和性能上取一较好折衷的结论。

LBG vector quantization algorithm is used to create codebook traditionally, but the sequence is not in order.

用LBG算法产生的码书，码书中的码向量在码书中的排列是无序的。

If is cyclic, then for every codeword the word is also a codeword.

必要条件：如果是循环码，那么仍然是码字，故线性码是理想。a是多项式，码字也看成是多项式。

The topics covered include the basic concepts of information theory--entropy, mutual information, channel capacity, information rate, Shannon's noiseless coding theorem and Shannon's fundamental coding theorem; modeling of information sources--zero-memory and Markov models; modeling of information channels--BSC and BEC channels, additivity of information and cascaded channels; construction of compact source codes--Kraft inequality, compact codes, Huffman and LZW compression codes; and analysis and design of error-control channel codes--Hamming distance, binary linear codes and the parity-check matrix, Hamming codes, checksum codes, cyclic codes and the generator polynomial and CRC codes.

课程的内容包括：信息论的基本概念（熵、交互信息、信道容量、信息率、 Shannon无噪声编码定理和Shannon基本编码定理）、信源模型（无记忆模型和Markov模型）、信息信道模型（BSC 和 BEC模型、信息的可加性和级联信道），紧致信源编码设计（Kraft不等式，紧致编码，Huffman 和LZW压缩编码）以及差错控制信道码的设计与分析（海明距离，二元线性码，奇偶校验矩阵，海明码，校验和，循环码，生成多项式和CRC码）。

The problem of finding stabilizer quantum-error-correcting codes can be transformed into the problem of finding classical self-orthogonal linear codes over the Galois field GF(4) under a Hermitian inner product. A classical cyclic code over the field GF(4) is self-orthogonal with respect to the Hermitian inner product iff the generator polynomial of its dual code is a factor of its generator polynomial.

寻找量子稳定子码的问题可以转化为寻找GF(4)上厄米内积自正交的经典线性码的问题；对于GF(4)上的经典循环码，它是厄米内积自正交的，当且仅当它的对偶码的生成多项式是其生成多项式的因子。

For the game, Rushing returned two punts for 94 yards (47.0 average) and three kickoffs for 73 yards (24.3 average), totaling 167 return yards.

全场比赛中，拉辛2次弃踢回攻共94码(平均每次47.0码)，3次开球回攻共73码(平均每次24.3码)，总计167码。

Before the search process, all codewords in the codebook are Hadamard-transformed and sorted in the ascending order of their first elements.

在编码前，该算法预先计算每个码字的哈德码变换，然后根据各码字哈德码变换的第一维系数大小的升序排列对码字进行排序。

10Gigabit Ethernet (10 GBASE-R and 10 GBASE-W) uses 64B/66B coding and decoding, which is the code format transform without the high transition density and its redundancy is small at the cost of complicated synchronization and the storage. Thus scramble is added to the 64B/66B and descramble is otherwise added before the 64B/66B decode.

它的10 GBASE-R和10 GBASE-W标准中物理编码层采用了64B/66B编解码方案。64B/66B码只是一种码的格式转换，并没有显著增加码的0、1转换密度。64B/66B编解码方案包括64B/66B码格式转换、扰码/解扰以及数据速率转换。64B/66B码冗余度很小，其代价是同步所需时间和资源相对较多。

The approach has been successfully used for determining the power rating of the motor of the pusher which is a part of a high speed palletizer modeled MDJ1600H.

本文的最后讨论了高位码垛和低位码垛的工作原理，根据高位码垛连续降过程的时序和进包时序，得出了换垛过程物料畅通与否的判据，根据高位码垛的工作特点，获得了码垛能力的表达式。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
