Research content 【 display / non-display

  • (Summary)An [n,k,d]q code means a linear code of length n, dimension k with minimum distance d over the field of q elements. We tackle the problem to optimize one of the parameters n,k,d for given the other two, which is called the optimal linear codes problem.

    (Keyword)optimal linear codes, Griesmer bound, finite projective space, extension of a linear code, pseudo-cyclic codes
