对于某个奇素数p
我们给出了判断2是
mod
p的三次剩余的一个引理
由此引理
我们定义了有限域F2上的6种三次剩余码;研究了6种三次剩余码之间的关系
得出了三次剩余码的码长、重量特征和极小汉明距离范围;最后给出了三次剩余码的对偶码的生成多项式
以及在选择适当的p次本原单位根的情况下
给出了它的生成幂等多项式.
For any odd prime
p
we give a lemma which is determined when 2 is a cubic residue modulo
. Using it
we define the notion of six cubic-residue codes over F
2
.We discuss the relations between six codes
and study the length of cubic-residue codes
character of weight and the bound of the minimum Hamming distance.We finally give the generator polynomials of dual codes
and the generating idempotents of cubic-residue code when choose the appropriate primitive p root of unity.
