The t-wise intersection and trellis of relative four-weight codes

Based on the applications of codes with few weights, we define the so-called relative four-weight codes and present a method for constructing such codes by using the finite projective geometry method. Also, the t-wise intersection and the trellis …


A class of subfield codes of linear codes and their duals

Recently, subfield codes of some optimal linear codes have been studied. In this paper, we further investigate a class of subfield codes and generalize the results of the subfield codes of the conic codes in Ding and Wang (Finite Fields Appl. 56 …


On conflict free DNA codes

DNA storage has emerged as an important area of research. The reliability of a DNA storage system depends on designing those DNA strings (called DNA codes) that are sufficiently dissimilar. In this work, we introduce DNA codes that satisfy the …


Self-dual codes over

In this study we consider Euclidean and Hermitian self-dual codes over the direct product ring F 2 × ( F 2 + v F 2 ) $\mathbb {F}_{2} \times (\mathbb {F}_{2}+v\mathbb {F}_{2})$ where v2 = v. We obtain some theoretical outcomes about self-dual …


Two families of subfield codes with a few weights

Subfield codes of linear codes over finite fields have recently received a lot of attention, as some of these codes are optimal and have applications in secrete sharing, authentication codes and association schemes. In this paper, two families of …
