VI-2 class of Hamming weight of -aryq linear codes with dimension 5

Abstract

The Hamming weight hierarchy of a linear [n,k;q] code c over GF(q)is the sequence(d1,d2,…,dk),where dr is the smallest support weight of an r-dimensional subcode of c.According to some new necessary conditions,the VI class Hamming weight hierarchies of q -ary linear codes of dimension 5 can be divided into six subclasses. By using the finite projective geometry method, VI-2 subclass and determine were researched almost all weight hierarchies of the VI-2 subclass of weight hierarchies of q -ary linear codes with dimension 5.
