Abstract and Keywords

Abstract: Linear codes with complementary duals (LCD) over finite fields have good structure and properties, and are widely used in two-user adder channels. In this paper, the quaternary Hermitian LCD constacyclic codes are constructed and their parameters are analyzed. The dimensions of these codes are settled and the lower bounds on their minimum distances are presented.

Keywords: linear codes with complementary duals(LCD); constacyclic codes; generator polynomial
