CRC的全称为Cyclic Redundancy Check，中文名称为循环冗余校验。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 Cyclic Redundancy Check, the Chinese name of the Cyclic Redundancy Check. It is an important class of linear block codes, encoding and decoding

1.编写（10，4）线性分组码，并求出最小距离 2.分别采用软硬判决，对线性分组码进行误码率分析-Writing the (10,4) linear block code, and 2 were used to determine the minimum distance of soft and hard decision for linear block code error rate analysis
