摘　　要：光正交码是适用于光纤CDMA系统的扩频序列。但在定义中并未给出构造、生成方法，本文研究的有限几何法是一种有效的光正交码设计方法，它可以设计出最优码。本文对此法原理、设计方法进行了研究，提出了一种计算机辅助设计方法，并给出了实际设计过程及结果。Optical orthogonal code(OOC)is one sort of the spread spectrum sequences used in fiber CDMA systems.Different from other sequences,the definition of OOC does not provide it's constructing method.The method from finite projective geometries introduced in this paper is a effective means of constructing OOC,by which we could construct optimal OOCs.The principle of this method will be presented in this paper,followed by an example of constructing OOC with the assistance of computer.
