一种基于光纤布拉格光栅的新型多址干扰消除方案

In order to effectively reduce the effects of multi-access interference on the performance of optical codedivision multiple access(CDMA)communication systems with intensity modulation and direct detection,according to group information,a novel kind of multi-access interference cancellation scheme based on fiber Bragggrating(FBG)used with two dimensional address code MPC/OOC is presented.Considering the effects ofmulti-access interference,avalanche photodiode(APD)noise,and thermal noise,the performance of proposedoptical CDMA communication systems is analyzed in detail.The result shows that this kind of multi-accessinterference cancellation scheme based on FBG can effectively reduce the influence of multi-access interference.And when received optical power is lager enough,the multi-access interference in two dimensional optical CDMAcommunication systems with MPC/OOC can be reduced completely.
