编写一程序验证CRC检错，利用线性编码理论，在发送端根据要传送的k 位二进制码序列，以一定的规则产生一个校验用的监督码（既CRC 码）r 位，并附在信息后边，构成一个新的二进制码序列数共(k+r)位，最后发送出去。在接收端，则根据信息码和CRC码之间所遵循的规则进行检验，以确定传送中是否出错。-Procedures for the preparation of a CRC error detection to verify the use of linear coding theory, in the sending end to send based on the k-bit binary code sequence, certain rules in order to produce a calibration with the supervision of code (both the CRC code) r-bit, with the information back to form a new sequence of binary code number of a total of (k+ r)-bit, and finally sent. At the receiving end, then in accordance with Code of information between the CRC code and the rules followed by tests to determine whether the error in transmission.
