Description: 上机实验（1）——CRC校验码（3学时）
实验要求：编写出CRC码的编码和解码程序。
(1)实验框架：CRC编码－信道传输－CRC解码。
(2)CRC编码将原始数据按照既定的生成多项式进行编码；
(2)信道传输中实现模拟信道，某些位数据随机发生差错；
(3)CRC解码要能准确判断是否有差错，无差错要恢复出原始数据。-On the experimental machine (1)- CRC checksum code (3 hours) Experimental requirements: preparation of a CRC code of the encoding and decoding procedures. (1) Experimental framework: CRC encoding- transmission channel decode-CRC. (2) CRC encoding the raw data generated in accordance with the established polynomial coding (2) channels for analog transmission channel, some random bits of data error (3) CRC decoder to be able to accurately determine whether there is any error, no errors to restore the original data.
