常循环码是线性码的一个子类,已经得到了很好的研究。常循环BCH码是常循环码的一族,并且包含BCH码作为子类。与BCH码的深入研究相比,常循环BCH码的研究相对较少。本文的目的是确定一类长度为设计距离的q元常循环BCH码的维数和最小距离。如将看到的,这些代码中的一些是最佳的。
Constacyclic codes are a subclass of linear codes and have been well studied. Constacyclic BCH codes are a family of constacyclic codes and contain BCH codes as a subclass. Compared with the in-depth study of BCH codes, there are relatively little study on constacyclic BCH codes. The objective of this paper is to determine the dimension and minimum distance of a class ofq-ary constacyclic BCH codes of lengthwith designed distancesfor. As will be seen, some of these codes are optimal.
