CRC校验原理

1、循环校验码（CRC码）：是数据通信领域中最常用的一种差错校验码，其特征是信息字段和校验字段的长度可以任意选定。

2、生成CRC码的基本原理：任意一个由二进制位串组成的代码都可以和一个系数仅为‘0’和‘1’取值的多项式一一对应。例如：-Principle 1 CRC checksum, cyclic checksum (CRC code): is the data communications of the most commonly used error checking code, which is characterized by the information field and verify the length of the field can be arbitrarily selected. 2, CRC code generated the basic principle: an arbitrary bit string formed by the binary code can be a factor of only ' 0 ' and ' 1'　values correspond to a polynomial. For example: ~ ~ ~
