双权$q$元线性码的构造

A construction of $q$-ary linear codes with two weights

Ziling Heng, Qin Yue

摘要:

低权线性码是编码理论中的一个重要问题,受到了广泛的关注。本文利用有限域上的迹函数和范数函数构造了$q$元线性码。在某些情况下,线性码的重量分布是基于高斯和确定的。有趣的是,我们的结构可以产生最佳或几乎最佳的代码。此外,我们表明,我们的代码可以用来构造秘密共享方案与有趣的访问结构和强正则图与新的参数。

英文摘要:

Linear codes with a few weights are very important in coding theory and have attracted a lot of attention. In this paper, we present a construction of $q$-ary linear codes from trace and norm functions over finite fields. The weight distributions of the linear codes are determined in some cases based on Gauss sums. It is interesting that our construction can produce optimal or almost optimal codes. Furthermore, we show that our codes can be used to construct secret sharing schemes with interesting access structures and strongly regular graphs with new parameters.
