摘要:

有限域上的线性码和循环码的壳由于其广泛的应用而引起人们的兴趣和广泛的研究。本文研究了环$\mathbb{Z}_4$上长度为$n$的循环码的壳,并利用商环$\mathbb{Z}_4[x]/\langle x^n-1\rangle$中的生成元作为理想建立了它们的特征.本文给出了计算$\mathbb{Z}_4$上任意奇长循环码壳类型的一个算法。建立了$\mathbb{Z}_4$上的奇长$n$循环码的壳的平均$2$维数$E(n)$.给出了$E(n)$的一般公式及其上下界。事实证明,$E(n)$的增长率与$n$相同。

英文摘要:

The hulls of linear and cyclic codes over finite fields have been of interest and extensively studied due to their wide applications. In this paper, the hulls of cyclic codes of length $n$ over the ring $\mathbb{Z}_4$ have been focused on. Their characterization has been established in terms of the generators viewed as ideals in the quotient ring $\mathbb{Z}_4[x]/\langle x^n-1\rangle$. An algorithm for computing the types of the hulls of cyclic codes of arbitrary odd length over $\mathbb{Z}_4$ has been given. The average $2$-dimension $E(n)$ of the hulls of cyclic codes of odd length $n$ over $\mathbb{Z}_4$ has been established. A general formula for $E(n)$ has been provided together with its upper and lower bounds. It turns out that $E(n)$ grows the same rate as $n$.
