循环冗余码的生成和验证:数字通信中的编码分为信源编码和信道编码两大类。为了提高数字通信的可靠性采取的编码称为信道编码，又称抗干扰编码。数字通信中为了尽可能地提高通信的可靠性，需要采用信道编码技术，对可能或已经出现的差错进行控制，CRC码就是其中的一种编码技术。本实验就是编写RCR编码，可以模拟发送信息，噪声加入，检测验证，信息重发的过程!(Cyclic redundancy code generation and validation: digital communication in the coding is divided into source coding and channel coding two broad categories. In order to improve the reliability of digital communications to the code known as channel coding, also known as anti-interference codes. Digital communication as much as possible in order to improve the reliability of communication need to use channel coding techniques, which may or may control the errors that have emerged, CRC code is one of a kind of coding techniques. RCR in this experiment is to write code that can simulate send a message, noise adding, testing verification, information, process re-issued!)
