摘要

本文通过在有限Galois域上建立仿射平面

以及在仿射平面上建立Steiner系统

研究了仿射平面上Steiner系统的存在性;分析了部分点阵与Steiner系统的关联;建立了Steiner系统参数与OOC码字参数的对应关系.据此提出了基于仿射平面上Steiner系统的OOC码字设计方案;给出了ST-OOC码字(

)的具体设计步骤和设计结果;分析了ST-OOC的码字性能和特点和灵活的码长码重对应关系;指明了ST-OOC码字的主要应用领域.

Abstract

According to the theory of t-designing

the corresponding relation between points array in finite Galois field and Steiner system has firstly been found

and then the existence of Steiner system in finite filed is researched.By connecting part points array with Steiner system

the parameter correspondence between optical orthogonal code and Steiner system has been established.After that

the designing process of ST-OOC has been researched in detail.The designing results of ST-OOC(

) has been given.The result indicates that ST-OOC has excellent performance and characters

such as the lowest cross-correlation

large cardinality and flexibility to choose code-length and code-weight

therefore ST-OOC is very appropriate to OCDMA system.At last

the application of ST-OOC have been has been discussed.
