Existence and Construction of LCD codes over Finite Fields
share
We demonstrate the existence of Euclidean and Hermitian LCD codes over finite fields with various parameters. In addition, we provide a method for constructing multiple Hermitian LCD (self orthogonal, self dual) codes from a given Hermitian LCD (self orthogonal, self dual) code, as well as a method for constructing Euclidean (Hermitian) LCD codes with parameters [n+1, k+1] and [n,k+1] from a given Euclidean (Hermitian) LCD code with parameters [n,k] over finite fields. Finally, we provide some findings on σ-LCD codes over finite fields.
