长度为两个素数乘积的循环码的分圆构造

Cyclotomic Constructions of Cyclic Codes with Length Being the Product of Two Primes

Cunsheng Ding

摘要:

循环码是一类有趣的线性码,由于其高效的编码和解码算法,在通信和存储系统中有着广泛的应用。他们已经研究了几十年,并取得了很大的进展。本文提出并分析了三种类型的二阶广义割圆和三类长度为$n_1n_2$,维数为$(n_1n_2+1)/2$的循环码,其中$n_1$和$n_2$是两个不同的素数.也证明了它们的最小似奇权的界。这三种构造在某些情况下产生最好的循环码。

英文摘要:

Cyclic codes are an interesting type of linear codes and have applications in communication and storage systems due to their efficient encoding and decoding algorithms. They have been studied for decades and a lot of progress has been made. In this paper, three types of generalized cyclotomy of order two and three classes of cyclic codes of length $n_1n_2$ and dimension $(n_1n_2+1)/2$ are presented and analysed, where $n_1$ and $n_2$ are two distinct primes. Bounds on their minimum odd-like weight are also proved. The three constructions produce the best cyclic codes in certain cases.
