On the number of ℤp-double cyclic codes and quasi cyclic codes

Journal of Algebra and Its Applications, 2023
In this paper, we study the class of [Formula: see text]-double cyclic codes of length [Formula: see text] We give a closed formula for the number of [Formula: see text] -double cyclic codes of length [Formula: see text] for any integers [Formula: see text] and [Formula: see text] that are relatively prime to [Formula: see text] Moreover, we give a ...

Cyclic polar codes

2015 IEEE International Symposium on Information Theory (ISIT), 2015
Arikan introduced polar codes in 2009 and proved that they achieve the symmetric capacity, under low-complexity successive cancellation decoding, of any binary-input discrete memoryless channel. Arikan's construction is based on the Kronecker product of 2-by-2 matrices and it was extended to larger matrices by Sasoglu et al. in 2010.

On cyclic DNA codes

2013 IEEE International Symposium on Information Theory, 2013
This paper considers cyclic DNA codes of arbitrary length over the ring R = F2[u]/(u4 - 1). A mapping is given between the elements of R and the alphabet {A, C, G, T} which allows the additive stem distance to be extended to this ring. Then, cyclic codes over R are designed such that their images under the mapping are also cyclic or quasi-cyclic of ...

Cyclic product codes

IEEE Transactions on Information Theory, 1965
A new class of cyclic codes, cyclic product codes, is characterized. These codes enjoy the implementation advantages of cyclic codes and, in addition, possess the important structural properties of product (iterated) codes. The main results are as follows: \begin{enumerate} \item Conditions are given which ensure that the product of two, and, hence ...

On Cyclic and Abelian Codes

IEEE Transactions on Information Theory, 2013
In this paper, the minimum weight and the dimension of all cyclic codes of length pn over a field Fq, are computed, when p is an odd prime and Fq a finite field with q elements, assuming that Fq generates the group of invertible elements of Zpn. Furthermore, the minimum weight and dimension of codes which are sum of two minimal codes in Fq(Cp×Cp) are ...

MULTIPLE-CYCLIC CODES

Journal of Cybernetics, 1976
In this paper the phasing aspects are considered in terms of cyclic blocks so that a code word is composed of several blocks, each block having a cyclic structure. The theory is analogically developed as in the classical case.

Locally testable cyclic codes

44th Annual IEEE Symposium on Foundations of Computer Science, 2003. Proceedings., 2004
Cyclic linear codes of block length n over a finite field F/sub q/ are linear subspaces of F/sub q//sup n/ that are invariant under a cyclic shift of their coordinates. A family of codes is good if all the codes in the family have constant rate and constant normalized distance (distance divided by block length).
