摘要
光正交码是用于光纤码分多址系统的一种优选地址码,它是一个0,1二元序列族,具有良好的相关特性.运用数论方法提出了2种新的递归构造法,在已知2个码字集合的基础上,通过生成不同的差分阵列,可构造出较多的新的码字集合.
The optical orthogonal code, which is a kind of preferred address code generally used in optical CDMA systems, is a family of binary （0,1）-sequences with good auto- and cross- correlation properties. In this paper ,two new recursion methods of construction of OOC are presented by the number-theoretic method,which can construct more new sets of codes from creating different difference matrix on the basis of two given sets of codes.
