1、(一)crc算法原理及c语言实现 1.crc原理介绍 crc的英文全称为cyclic redundancy check(code),中文名称为循环冗余校验(码)。它是一类重要的线性分组码,编码和解码方法简单,检错和纠错能力强,在通信领域广泛地用于实现差错控制。 crc计算与普通的除法计算有所不同。普通的除法计算是借位相减的,而crc计算则是异或...

多项式编码(polynomial code),也称为CRC(cyclic redundancy check,循环冗余校验码),多项式编码的思想是:将位串看成是系数为0或1的多项式。CRC校验保护的单位是数据块。数据块的大小根据实际情况而定。每一个数据块均被看作是一个二进制多项式,即所有系数均为二进制(即1或0)的多项式。
