摘要: 研究循环码周期分布的反问题,即对于给定的正整数n和非负整数序列{A1,A2,…,An},是否存在Fq上的某个[n,k]-循环码,使得其周期分布恰好为{A1,A2…,An}.

关键词: 周期分布, 循环码, 分圆多项式

Abstract: This paper studies the inverse question of period distribution of cyclic codes——whether there exists some[n,k]-cyclic codes over finite field Fq for a given positive integer n and a nonnegative integer sequence {A1,A2,…,An},so that the period distribution of these codes is exactly {A1,A2,…,An}.

Key words: cyclic codes, period distribution, cyclotomic polynomial
