Let K be a set of positive integers and let G be an additive group. A 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 does not depend on k. In this paper, we determine a balanced difference packing of the largest possible size whenever uv is odd. The corresponding optimal balanced optical orthogonal signature pattern codes are also obtained.

设K是一组正整数,设G是一个可加组。一差异打包是G 的一组子集,其大小来自K,其差异列表最多覆盖G 的每个元素一次。如果大小的块数是平衡的不依赖于k。在本文中,我们确定了一个平衡的当uv为奇数时,最大可能尺寸的差异包装。相应的最优平衡 还获得了光学正交签名模式代码。
