一类三重循环码

A Class of Three-Weight Cyclic Codes

Zhengchun Zhou, Cunsheng Ding

摘要:

循环码是线性码的子类,并且由于它们具有有效的编码和解码算法而在消费电子、数据存储系统和通信系统中具有应用。本文给出了一类环$\gf(p)$上的三重循环码,其中$p$为奇素数,其码元具有两个零点.解决了这类循环码的重量分布问题。有些循环码是最优的。本文还研究了循环码的一个子类的循环码,并证明了它是最优的。

英文摘要:

Cyclic codes are a subclass of linear codes and have applications in consumer electronics, data storage systems, and communication systems as they have efficient encoding and decoding algorithms. In this paper, a class of three-weight cyclic codes over $\gf(p)$ whose duals have two zeros is presented, where $p$ is an odd prime. The weight distribution of this class of cyclic codes is settled. Some of the cyclic codes are optimal. The duals of a subclass of the cyclic codes are also studied and proved to be optimal.
