Quasi-cyclic and generalized quasi-cyclic codes and uniqueness of their generators

Discrete Mathematics, Algorithms and Applications, 2022
In this paper, we use a novel approach to describe generator polynomials of quasi-cyclic (QC) and generalized QC (GQC) codes over finite fields. Our study of QC- and GQC-codes will be general and not only restricted to one-generator codes. We prove that generator polynomials of QC-codes and GQC-codes are unique.

Binary Quasi-Cyclic Goppa Codes

Designs, Codes and Cryptography, 2000
A class of quasi-cycic Goppa codes containing irreducibles codes, and partially split ones, is defined. A necessary and sufficient condition for a Goppa code to be quasi-cyclic is given. One more sufficient condition is derived on the defining polynomial of the Goppa code.

On quasi-cyclic codes

Proceedings. 1998 IEEE International Symposium on Information Theory (Cat. No.98CH36252), 2002
Many binary quasi-cyclic codes have a better minimum distance than other known linear codes with the same parameters. We present 43 new quasi-cyclic codes, which improve on the parameters of previously found quasi-cyclic codes. Five of them even improve the lower bound on the minimum distance for linear codes.

A SPECIAL CLASS OF QUASI-CYCLIC CODES

Bulletin of the Australian Mathematical Society, 2017
We study a special class of quasi-cyclic codes, obtained from a cyclic code over an extension field of the alphabet field by taking its image on a basis. When the basis is equal to its dual, the dual code admits the same construction. We give some examples of self-dual codes and LCD codes obtained in this way.
