Cyclic codes over finite rings
It is well known that cyclic linear codes of length n over a (finite) field F can be characterized in terms of the factors of the polynomial x"-1 in F[x]. This paper investigates cyclic linear codes over arbitrary (not necessarily commutative) finite tings and proves the above characterization to be true for a large class of such codes over these rings.

متن کاملFree Cyclic Codes as Invariant Submodules over Finite Chain Rings
By applying the theory of linear algebra, one can obtain some properties of these codes which generalize several well known results for free cyclic codes represented in [1, 4]. Mathematics Subject Classification: 94B05, 11T71, 47A15
متن کاملCyclic Codes over Some Finite Rings
In this paper cyclic codes are established with respect to the Mannheim metric over some finite rings by using Gaussian integers and the decoding algorithm for these codes is given. AMS Classification: 94B05, 94B60
متن کاملQuasi-Cyclic Codes Over Finite Chain Rings
In this paper, we mainly consider quasi-cyclic (QC) codes over finite chain rings. We study module structures and trace representations of QC codes, which lead to some lower bounds on the minimum Hamming distance of QC codes. Moreover, we investigate the structural properties of 1-generator QC codes. Under some conditions, we discuss the enumeration of 1-generator QC codes and describe how to o...
متن کاملContraction of Cyclic Codes Over Finite Chain Rings
Let R be a commutative finite chain ring of invariants (q ,s ), and Γ(R) the Teichmüller’s set of R. In this paper, the trace representation cyclic R -linear codes of length l, is presented, when gcd(l,q ) = 1. Wewill show that the contractions of some cyclic R -linear codes of length ul are γ -constacyclic R -linear codes of length l, where γ ∈ Γ(R)\{0R} and themultiplicative order of γ is u .
