摘要 采用布拉格光纤光栅(FBG)作为编解码器的跳频时延(WHTS)OCDMA系统中,FBG制作不完善会导致FBG编解码器之间的不匹配,这种不匹配会引入一种新的噪声,称之为FBG编解码噪声.就这种噪声对跳频时延OCDMA系统的影响进行了分析,并就一定不匹配程度对跳频时延OCDMA系统的影响情况作出仿真,对其新的误码率函数进行了推导,发现FBG编解码噪声对不同的系统速率,系统性能带来不同程度的影响. In the system of wavelength hopping time-spreading(WHTS)optical code-division multiple access(OCDMA) system with fiber Bragg grating(FBG) as coder decoder(CODEC),FBG′s imperfect making would cause FBG CODEC mismatching with each other.This mismatching would introduce new kind of noise,which was called FBG CODEC noise.The influence of such kind of noise to WHTS OCDMA system was analyzed.Simulation experiment was carried out for WHTS OCDMA system with fixed FBG CODEC mismatching degree,the new BER function produced by this mismatching was deducted too,and it was found that FBG CODEC noise caused varying degrees influence to WHTS OCDMA system performance with different system bit rate.
