Let R be an arbitrary commutative finite chain ring with $$1\ne 0$$ . 1-generator quasi-cyclic (QC) codes over R are considered in this paper. Let $$\gamma $$ be a fixed generator of the maximal ideal of R, $$F=R/\langle \gamma \rangle $$ and $$|F|=q$$ . For any positive integers m, n satisfying $$\mathrm{gcd}(q,n)=1$$ , let $$\mathcal{R}_n=R[x]/\langle(More)

First, we give a canonical form decomposition for additive cyclic codes over R. This decomposition is used to(More)
In this paper, we study the construction of cyclic DNA codes by cyclic codes over the finite chain ring     2 4 1 F u u . First, we establish a 1-1 correspondence  between DNA pairs and the 16 elements of the ring     2 4 1 F u u . Considering the biology features of DNA codes, we investigate the structure and properties of self-reciprocal(More)
