The structure of generalized quasi cyclic codes

2005
The structure of generalized quasi-cyclic (GQC) codes is investigated. These are codes in which a permutation automorphism has orbits of varying lengths on the coordinate positions. A BCH-type bound is derived which is similar to that for quasi-cyclic (QC) codes.

Quasi-cyclic Goppa codes

2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002
In this paper, we construct quasi-cyclic Goppa (or related) codes. Some of these codes reach the parameters of best known codes. Generally, there is no known quasi-cyclic code for these lengths and dimensions.
