Description: 在计算机和各类数据通信中传递二进制信号的时候，由于存在各种干扰，会使得传递的信息发生失真现象，这时候就要用到纠错码。
为了能够发现或纠正编码中的错误，我们必须通过一定的手段来对信息的编码谨慎选择，经过选择的编码在出错的时候能够很容易的发现和纠正。比如我们选择了编码{000,111}，当传输中发生了一位错，我们就能够发现并纠正，比如收到的编码是001，我们就可以将它纠正为000。
汉明距离用于表示两个码字中不同位的数目。群码是一种纠错码，根据群码中不同的汉明距离，群码可以保持一定的纠错能力。
直接压缩-in various computer and data communications transmission of binary signals, because of the existence of all kinds of interference, would allow transfer of information distortion occurred, this time will be used error-correcting codes. In order to be able to detect or correct coding errors, we must adopt certain measures to information on the coding prudent choice, selected coding error in the time can be easily found and corrected. For instance, we chose to 000,111) (coding, transmission occurred one mistake, we will be able to detect and correct, For example, before the code is 001, we can rectify it to 000. Hamming distance is used to mean two different code word the number. Group code is error-correcting codes, group codes different Hamming distance, group codes can maintain a certain e Platform: |

Description: 如果你可以编写出合格的代码，但是想更进一步、创作出组织良好而且易于理解的代码，并希望成为一名真正的编程专家或提高现有的职业技能，那么《编程匠艺——编写卓越的代码》都会为你给出答案。本书的内容遍及编程的各个要素，如代码风格、变量命名、错误处理和安全性等。此外，本书还对一些更广泛的编程问题进行了探讨，如有效的团队合作、开发过程和文档编写，-Many programmers know how to write correct code- code that works. But not all know how to craft great code- code that is well written and easy to understand. Code Craft teaches programmers how to move beyond writing correct code to writing great code. The book covers code writing concerns, including code presentation style, variable naming, error handling, and security and the wider issues of programming in the real world, such as good teamwork, development processes, and documentation. Code Craft presents language-agnostic advice that is relevant to all developers, from an author with loads of practical experience. A Q&A section at the end of each chapter helps readers to review the material and makes the book suited for academic use as well.

-Error-controlled coding techniques are used to detect and/or correct errors that occur in the message transmission in a digital communications system. Wireless personal channels used by mobile communications systems and storage systems for digital multimedia data all require the implementation of error control coding methods. Demonstrating the role of coding in communication and data storage system design, this text illustrates the correct use of codes and the selection of the right code parameters. Relevant decoding techniques and their implementation are discussed in detail. Providing communication systems engineers and students with guidance in the application of error-control coding, this book emphasizes the fundamental concepts of coding theory while minimising the use of mathematical tools.

关于输入文件格式：
没有考虑对lex输入文件的出错处理，所以输入文件务必严格书写正确。
Lex中的正规表达式使用了以下运算符：
[] | * @ ( )
并且正规表达式中不能出现其他的子正规表达式。
如果想要在待识别的正则式中使用上述运算符，请使用转义符号，即\。
例如，如果想用*，可以写成\*

Description: 循环码是线性分组码中最重要的一种子类，是目前研究得比较成熟的一类码。它的检、纠错能力较强，编码和译码设备并不复杂，而且性能较好，不仅能纠正随机错误，也能纠正突发错误。循环码还有易于实现的特点，很容易用带反馈的移位寄存器实现其硬件 。循环码具有许多特殊的代数性质，这些性质有助于按照要求的纠错能力系统地构造这类码，并且简化译码算法，目前发现的大部分线性码与循环码有密切关系正是由于循环码具有码的代数结构清晰、性能较好、编译码简单和易于实现的特点，因此在目前的计算机纠错系统中所使用的线性分组码几乎都是循环码。-Cyclic code is a linear block code in a subclass of the most important, is the more mature studied a class of code. Its inspection, error correction ability, encoding and decoding equipment is not complicated, and the performance is better, not only can correct random errors, burst errors can be corrected. Cyclic codes also easy to implement features, it is easy to use feedback shift registers with its hardware. Cyclic code has a number of special algebraic properties, these properties contribute to the error correction capability as required to construct this type of system code, and simplifies the decoding algorithm, currently found in most linear codes and cyclic codes are closely related it is precisely because cyclic code with the code of the algebraic structure of a clear, better performance, encoding and decoding features simple and easy to implement, so the correction in the current computer system used by almost all linear block codes, cyclic codes.
