摘要

对循环冗余校验的研究及应用大多集中在错误检测，很少应用其纠错功能。IEEE802.11 标准中使用CRC码对接收的信息帧进行错误检测。在介绍生成CRC码的基本方式的基础上，论文详细分析了纠正信息帧中单比特错误的方法。

Abstract

The researches on CRC mainly focus on error detection, seldom on the function of error correction. IEEE 802.11 standard makes use of cyclic redundancy code to detect the error. Based on introducing the essential method of generating CRC, this paper analyses the process of correcting a single bit error in the information frame of IEEE 802.11 standard in detail.
