Study of the depth spectrum of some linear codes on the ring Z_4
Shixin Zhu · Journal of Hefei University of Technology · 2007
It is proved in the paper that the depth spectrum of linear codes of the type 2k over the ring Z4 consists exactly of k nonzero values.In addition,in light of the isomorphism between the linear subcodes of the type 2k and the linear codes over the Galois field F2,the property of the depth spectrum of linear codes of the type 4k12k2 is researched,and the depth spectrum of some linear codes which fulfill certain specific conditions is given.
