二维码OCDMA通信系统的研究

Communication System of Two-Dimensional Optical Code-Division Multiple Access

介绍了光正交码和二维光正交码的概念,并对其性能进行了讨论。分析了T/S OCDMA、WDM+OCDMA、MW OCDMA三种二维码OCDMA系统,并比较了其性能。给出了二维光正交码光纤延迟线编解码器的设计方案和二维光正交码光纤光栅编码原理。

The concepts of optical orthogonal code and two-dimensional optical orthogonal code are introduced , and their performance is analysed .The paper analyses three types of two-dimensional optical code-division multiple access communication systems: T/S OCDMA、WDM+OCDMA、MW OCDMA, and compares their performance. The design of two-dimensional optical orthogonal code fiber delay line encoder and decoder, and the scheme of the encoder based on fiber grating is presented.
