  • In order to effectively reduce the effects of multi-access interference on the performance of optical code division 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 Bragg grating(FBG)used with two dimensional address code MPC/OOC is presented. Considering the effects of multi-access interference, avalanche photodiode (APD) noise, and thermal noise, the performance of proposed optical CDMA communication systems is analyzed in detail. The result shows that this kind of multi-access interference 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 CDMA communication systems with MPC/OOC can be reduced completely.
