最近,已证明(字段)的(QC)代码(QC)代码(线性)代码已显示出在编码理论中产生有用的结果。结合了这两个想法,我们研究Z(4)-QC代码,并使用通常的灰色地图获得新的二进制代码。在新代码中,著名的Golay代码升至Z(4)产生新的二进制代码,A(92,2(24),28)代码,这是所有二进制代码(线性或非线性)中最好的二进制代码。 。此外,我们根据其发电机多项式来表征与自由模块相对应的循环代码。
Recently, (linear) codes over 24 and quasi-cyclic (QC) codes (over fields) have been shown to yield useful results in coding theory. Combining these two ideas we study Z(4)-QC codes and obtain new binary codes using the usual Gray map. Among the new codes, the lift of the famous Golay code to Z(4) produces a new binary code, a (92, 2(24), 28)-code, which is the best among all binary codes (linear or nonlinear). Moreover, we characterize cyclic codes corresponding to free modules in terms of their generator polynomials.
