二进制非对称纠错码（AECC）在以二进制对称信道（Z信道）为模型的通信系统中起着重要的作用。Varshamov利用V h-序列构造了一般的二元AECC，并得到了许多好的二元AECC。本文给出了代数函数域射线类群中Vh-序列的一般构造。我们的构造导出了二进制AECC的新下界，改进了[18]中的结果。
Binary asymmetric error-correcting codes (AECC) play an important role in communication systems modeled by the binary symmetric channel (Z-channel). Varshamov proposed a general construction of binary AECC via V h-sequences and obtained many good binary AECC. In this paper, we give a general construction of V h-sequences in ray class groups of algebraic function fields. Our construction induces new lower bounds for binary AECC which improves the results in [18].
