basing on optics orthogonal codes,this paper proposes a new design scheme of three-dimension optics orthogonal codes.in this scheme,the optics orthogonal codes can be coded not only in space-domain,in time-domain,but also in frequency-domain.it has good auto-cross relativity properties.the simulation figures show that can enlarge the coeds capacity and improve the optics optical communications system performance.so it will be of interesting in coming high dense communication system.

摘 要：基于光正交码编码技术，提出了一种新型空/时/频三维ooc的设计方案，对光信号在时、频和空域进行编码，该码具有理想的自/互相关特性。通过仿真比较，在容量和系统的误码率等性能方面比一、二维ooc都有较大的提高，因而能很好地适应未来高密集光纤通信。关键词：三维光正交码；光码分多址；误码率；高密集光纤通信
