本文主要研究由常循环码产生的自对偶码。本文给出了长度大于0的Hermitian自对偶常循环码存在的充要条件。作为这些充分必要条件的应用，得到了MDS厄米特自正交和自对偶常循环码存在的一些条件。
This paper is devoted to the study of self-dual codes arising from constacyclic codes. Necessary and sufficient conditions are given for the existence of Hermitian self-dual constacyclic codes overof length. As an application of these necessary and sufficient conditions, some conditions under which MDS Hermitian self-orthogonal and self-dual constacyclic codes exist are obtained.
