光正交码

Optical Orthogonal Code

OCDMA技术已成功应用于无线通信领域,它具有抗干扰,提高系统容量等优点。本文对实现OCDMA技术关键的光地址码中较成熟的光正交码进行了介绍。阐述了光正交码的众多构造方法和现有的存在性结果,主要介绍了如何利用组合设计的方法构造光正交码。

OCDMA technology has been successfully applied in the field of wireless communication,it has a lot of advantages such as anti-jamming,improving system capacity etc.. This paper introduces the more mature optical orthogonal code in the optical address codes which achieve the key technology of OCDMA. We also expound many construction methods of optical orthogonal codes and exis-ting existence results. This paper mainly introduces how to use the method of combination design to construct optical orthogonal code.
