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 called the English Cyclic Redundancy Check (Code), the Chinese name for the Cyclic Redundancy Check (code). It is important for a class of lin

线性分组码的线性是指码组中码元间的约束关系为线性；分组是指编码时将每k个信息位一组进行独立处理，变换成长度为n (n>k) 的二进制码组。-Linear block code is a linear code group code element binding relationship between the linear group is to encode the information bits of each set of k-independent processing, t
