Among the existing LDPC codes, some codes have large girths but they have small minimum weights which lead to a poor BER performance.

论文摘要：由于短环和最小码重特性未得到重视时，可编码的不规则准循环LDPC码由规则准循环LDPC码导出可能导致其具有劣化的误码率性能。

In this paper, a low complexity and memory-efficient concatenated codes called Parallel Interleaved Concatenated Gallager Codes are presented.

本文提出了一种具有低复杂度和低存储需求的并行级联码—并行交织级联Gallager码。

Lastly, anti-jamming method based on jittering orthogonal codes at different moments is studied, orthogonal codes are searched with the genetic algorithm, and random initial phase is also used in this method, so great anti-jamming performance is gotten, and the performance is testified through the simulation.

提出了基于正交编码捷变的抗干扰方法，使用遗传算法搜索正交编码集，在不同的慢时刻使用相互正交的编码信号，并与随机初相方法相结合，有效地抑制了基于转发的有源干扰。

Besides the 30,000 frequently used phrases, there are 12 professional word-stocks are appended. The new function to construct phrases from taking the Characters from the screen and delete the phrases from the word-stock is convenient and agile. Also the Wangma Intellectual Pinyin Input Method is designed to the software. The unique Help and encoding prompt functions are added to the new software. The originated 'Retractile Antenna' Character sets switch method reduces identical codes greatly so as to improve the inputting speed greatly. The software adopts new simplified and traditional Character Roots list and originally creates the Three Grades to learn the Cross-codes that enables the beginners to learn the Method easily.

除系统自带的3万条常用词汇外，还特别设计了12种专业词库共10万条专业词汇，用户可以灵活选用；设计了屏幕取字造词功能，随造随用，灵活增删；增加了独特的&帮助&及编码提示功能；首创了&拉杆天线&式字集切换法，进一步减少了重码，使输入效率大为提高；推出了简繁兼备、配曲可唱的新字根表；安装了辅助的&王码智能拼音输入法&；独创了&识别码三段学习法&，为初学者由初级向高级过渡架设了阶梯。

In view of the status that a confused application of codes happened in the area of semeiology, and to differentiate the difference between periodical code and its language and photo codes, the author plans to use the concept of "sign and code" to describe specially the commercial code which circulates in the contemporary social culture and co-use with media symbol.

这充分体现出本文独特的文化观察视角。鉴于符号学中各符号概念之间的混用情况，并区分期刊符号与其使用的语言、图像等媒介符号之间的差别，笔者拟用符码概念，专门指称在当下社会文化背景中流通的，与媒介符号套合使用的产品符号。

It proceeds decoding by combining the least weight columns of check matrix of linear block codes. And it can also compute the soft output of decoded symbols, so an iterative decoder for product codes can constructed from it.

该算法通过组合线性分组码校验矩阵中权重较小的列向量进行译码并正确计算出各码字元素的软输出信息，应用该算法可以构造乘积码迭代译码器。

On the base of codes in 1989,a series of seismic measures are improved in new codes,such as limit of inner-storey drift angle,minimum reinforced rate,column-beam moment magnification coefficient and moment magnification factor at the column base,etc.

在89规范的基础上，本次规范修订进一步提高了包括层间位移角限值、最小配筋率、柱一梁级差系数等等在内的一系列抗震设计措施。

Reliable multicast solutions based on this technology include data carousels based on multiple transmissions, block encoding based on Reed-Solomon codes, and digital fountains based on fountain codes .

基于该技术的可靠组播解决方案主要包括：基于重复传输的数据轮播解决方案，基于RS码(reed-solomon codes)的分块编码解决方案，以及基于喷泉码的数字喷泉解决方案。

Basic information about the parties concerned, including their name, their customs registration codes, customs registration codes for customs declarers, and their addresses, etc.

当事人的基本情况，包括当事人姓名或者名称、海关注册编码、报关员海关注册编码、地址等

The 1-generator quasi-cyclic codes and their duals are the most frequently encountered QC codes in the literature.

单生成元的拟循环码及其对偶码是拟循环码中研究最多的一种。Séguin在要求x~m-1在F_q及F_中具有相同的分解的条件下，讨论了单生成元的拟循环码的结构及计数。
