LCD codes obtained from weakly p-self-orthogonal designs
A 1-design is weakly p-self-orthogonal if all the block intersection numbers give the same residue modulo p. In [1], we analyze extensions of the incidence matrix, orbit matrix, and submatrices of the orbit matrix of a weakly p-self-orthogonal 1-design in order to construct self-orthogonal codes. A linear code is called LCD code if the intersection with its dual code is trivial. Matrix G generates an LCD code if and only if det(GG^T) is nonzero (see [3]). We extend the methods of construction described in [1] in order to construct LCD codes over finite fields. We use suitable extensions of incidence matrix, orbit matrices, and submatrices of orbit matrices in order to construct LCD codes over a finite field. We will present examples of LCD codes constructed from weakly p-self- orthogonal designs obtained from groups using the construction described in [2]. [1] V. Mikulić Crnković, I.
