组LCD和组可逆LCD代码

Group LCD and Group Reversible LCD Codes

Steven T. Dougherty, Joe Gildea, Adrian Korban, Adam M. Roberts

摘要:

本文给出了一种构造LCD码的新方法。我们采用群环和一个众所周知的映射,发送群环元素的子环的$n \times n$矩阵,以获得LCD代码。我们的构造方法保证了我们的LCD码也是群码,即码是群环中的理想。证明了在群环元素$v,$上满足一定条件的情况下,可以构造非平凡群LCD码.此外,我们还表明,通过增加更多的限制,对群环元素$v,$可以构造群LCD码是可逆的。我们提出了许多二进制群LCD码的例子,其中一些是最佳的和具有不同参数的群可逆LCD码。

英文摘要:

In this paper, we give a new method for constructing LCD codes. We employ group rings and a well known map that sends group ring elements to a subring of the $n \times n$ matrices to obtain LCD codes. Our construction method guarantees that our LCD codes are also group codes, namely, the codes are ideals in a group ring. We show that with a certain condition on the group ring element $v,$ one can construct non-trivial group LCD codes. Moreover, we also show that by adding more constraints on the group ring element $v,$ one can construct group LCD codes that are reversible. We present many examples of binary group LCD codes of which some are optimal and group reversible LCD codes with different parameters.
