| 摘 要： | 提出了一种二维时间/波长、大容量、可共享的光码分多址(OCDMA)解编码器,以很少的硬件实现多用户的应用.编解码器利用阵列波导光栅实现多用户的同时共享,通过可编程的结构对OCDMA的编程,实现对其他用户的再分配.该OCDMA系统利用二维时间/波长Reed-Solomon 码,降低了硬件的数量.运用VPI软件模拟该系统,得到了眼图和BER结果,验证了系统的性能.

| Abstract: | One two-dimensional(2-D) temporal/ wavelength large capacity shared-type optical code division multiple access(OCDMA) encoder/decoder which can cover larger number of subscribers with sharable less amount of implementing hardware is proposed.The encoder/decoder can be shared by many users simultaneously through arrayed waveguide grating and the already used OCDMA codes can be re-allocated to other users by proposed programmable structure.The system employs generalized multi-wavelength Reed-Solomon code,which minimizes implemented hardware.The performance of the proposed OCDMA system is demonstrated in terms of its eye diagram and BER by using a numerical modeling software package such as VPI. |
