摘要
设计并制作了基于光纤光栅的光编码/解码器,实现单干扰用户、数据速率2.5Gb/s的码位重叠快跳频OCDMA(SO-FFH OCDMA)实验系统。分析SO-FFH OCDMA系统中的多址干扰,并与传统FFH OCDMA系统中的多址干扰进行比较。实验结果表明,多址干扰将恶化SO-FFH OCDMA系统性能,在单个干扰用户的条件下,该系统仍能正确解码数据速率2.5Gb/s的用户数据信息。
Optical encoders/decoders based on fiber gratings are designed and fabricated.Experiment on one interference user 2.5Gb/s symbol overlapping optical fast frequency-hopping CDMA(SO-FFH OCDMA) sys-tem was demonstrated.Multi-access interference in SO-FFH OCDMA system is studied,and is compared with that of traditional FFH OCDMA system.Experiment result shows that multi-access interference will de-grade the system performance.With one interference user,SO-FFH OCDMA can also decode data correctly at data bit rat...
