关于平衡$(Z_{4u}\times Z_{8v},\{4,5\},1)$差分填充

On balanced $(Z_{4u}\times Z_{8v},\{4,5\},1)$ difference packings

Hengming Zhao, Rongcun Qin, Dianhua Wu

摘要:

设$K$是一个正整数集合,$G$是一个加法群。$(G, K, 1)$差异包装是$G$的子集的集合,其大小来自$K$,其差异列表最多覆盖$G$的每个元素一次。如果大小为$k\in K$的块数不依赖于$k$,则它是平衡的。在本文中,我们确定了一个平衡的$(Z_{4u}\times Z_{8v},{4,5},1)$差异包装的最大可能的大小时,$uv$是奇数。得到了相应的最优平衡$(4u, 8v,\{4,5\},1)$光正交签名模式码。

英文摘要:

Let $K$ be a set of positive integers and let $G$ be an additive group. A $(G, K, 1)$ difference packing is a set of subsets of $G$ with sizes from $K$ whose list of differences covers every element of $G$ at most once. It is balanced if the number of blocks of size $k\in K$ does not depend on $k$. In this paper, we determine a balanced $(Z_{4u}\times Z_{8v},{4,5},1)$ difference packing of the largest possible size whenever $uv$ is odd. The corresponding optimal balanced $(4u, 8v,\{4,5\},1)$ optical orthogonal signature pattern codes are also obtained.
