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, transformation growth of degree n (n>　k) of binary code group.
