摘要
本文研究了环R=F2+vF2上线性码的深度分布和深度谱.利用环R到F2加群的两个同态映射及R上线性码的生成矩阵,给出了环R上4k12k22k3型线性码的深度谱的上下界.
In this paper,the depth distribution and the depth spectra of linear codes over ring R = F2 ＋ vF2 are studied.By using two homomorphisms of Abelian groups from R to F2 and the generator matrices of the codes over R,the upper bound and lower bound of the depth spectra of linear codes of type 4k12k22k3 are obtained.
