摘要
(z,u)-非覆盖族(cover-free family)的关联矩阵是一个(z,u)-二元叠加码.定义了一个(u+z)阶u-排列矩阵,利用u-排列矩阵研究了(z,u)-二元叠加码的结构、性质及其码率.
The incidence matrix of(z,u)-cover-free family is a binary superimposed(z,u)-code Notions of(u+z) order u-permutation matrix were defined,and their constructions and properties and ratio of(z,u)-code were studied by the(u+z) order u-permutation matrix.
