| 摘 要： | 基于光正交码,研究了WDM+OCDMA系统的性能。采用4个波长信道和3个码字的光正交码OOC(37,4,1),对12个用户的WDMA+OCDMA进行了系统仿真,用户数据速率为1Gbit/s,单模光纤长为50km,色散补偿光纤长为5km。如需增加WDMA+OCDMA的用户数,可以通过增加波长信道数或码字容量来实现。分析了色散效应对WDMA+OCDMA系统性能的影响,研究了用户之间相对延时对多址干扰和系统性能的影响。

| Abstract: | The performance of WDM+OCDMA system was analyzed based on optical orthogonal codes(OOCs).Employing four wavelength channels and three OOCs,simulations were performed on a 12-user WDMA+OCDMA system with the data rate of 1 Gbit/s,single mode fiber(SMF) of 50 km and dispersion compensation fiber(DCF) of 5 km.Increasing the number of users can be realized by adding wavelength channels or OOCs.The influence of dispersion effect on WDMA+OCDMA system was analyzed,and the effects of relative delays on the multiple-access interference and system performance were also researched. |
