在通信过程中用C语言实现CRC校验

The Usage of Checking CRC in Communication by C Language

通信的目的是要把信息及时可靠地传送给对方,因此要求一个通信系统传输消息必须可靠与快速,在数字通信系统中可靠与快速往往是一对矛盾。为了解决可靠性,通信系统都采用了差错控制。本文简述CRC算法原理,给出一种查表计算方法,并给出用C语言编写的算法源程序。

The purpose of communication is to send the information reliable to the other side in time, so we need a communication system which can send information both reliable and fast. But in digital communication system, fast and reliable of sending the information is often antinomy. In order to solve the problem, communication system all adopts error control. This paper details on the CRC arithmetic principium, giving out a method of consulting table, and shows the source program of arithmetic which is written by C language program.
