利用一阶广义Reed-culler码的张量积构造,将(Z(4),delta(L))与(Z(2)(2),delta(H))之间的Gray等距概念推广到有限链环上.我们的方法覆盖了卡莱,Constantinescu,Nechaev等人的结果,并与海瑟等人和Hanold等人的结果重叠。在Z(9)上应用Gray等距,我们得到了一个未知的非线性三进制(36,3(12),15)码.
Using tensor product constructions for the first-order generalized Reed-culler codes, we extend the well-established concept of the Gray isometry between (Z(4), delta(L)) and (Z(2)(2), delta(H)) to the context of finite chain rings. Our approach covers previous results by Carlet, Constantinescu, Nechaev et al, and overlaps with Heise et al. and Hanold ct ar. Applying the Gray isometry on Z(9) we Obtain a previously unknown nonlinear ternary (36, 3(12), 15) code.
