摘要
通过定义环F2+uF2上码字的深度,给出了计算该环上码字深度的递归算法,讨论了该环上码字深度的一些性质,进而研究了该环上线性码的深度分布和深度谱,给出了一类线性码的深度分布.
Based on the concept of the depth of a codeword over ring F2 ＋uF2, the recursive algorithm for computing the depth of a codeword over this ring was given, and a number of properties of the depth of a codeword were discussed. Furthermore, the depth distribution and the depth spectrum of linear codes over this ring were studied, and the depth distribution of a class of linear code was obtained.
