The combinatorics of LCD codes: Linear Programming bound and orthogonal matrices (1506.01955v1)
Published 5 Jun 2015 in cs.IT and math.IT
Abstract: Linear Complementary Dual codes (LCD) are binary linear codes that meet their dual trivially. We construct LCD codes using orthogonal matrices, self-dual codes, combinatorial designs and Gray map from codes over the family of rings $R_k$. We give a linear programming bound on the largest size of an LCD code of given length and minimum distance. We make a table of lower bounds for this combinatorial function for modest values of the parameters.
