CRC编码与检错性能分析

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、快速。通信系统采用差错控制解决数字通信系统中的不可靠性问题,差错控制编码是数据传输过程中普遍采用的提高数据通信可靠性的方法。CRC(CyclicRedundancy Check)是一种在实际通信中应用很广泛的差错控制编码,具有很强的检错能力。介绍了循环冗余校验CRC的差错控制原理及其特点,并给出了采用C语言程序对此算法检错性能的仿真分析。

Analysis of CRC Encoding and Performance of Error Detection

Sending timely and reliable information to each other is the purpose of the communication.So the messages sent by a communication system must be reliable and timely.A communication system adopts error control to solve the unreliability.Error control coding is commonly used as a data transmission process to improve the reliability of data communication,while the CRC is an error control coding which is used extensively in actual fact,and have a strong capability to detect the error.This paper describes the theory and feature of Cyclic Redundancy Check,and gives the analysis of the checking performance of this algorithm using simulation analysis with C language.
