摘　　要：为了克服多址干扰(MAI)对光码分多址(OCDMA)通信系统性能的影响,针对提出的二维地址码MPC/OOC,研究了一种基于组信息的并行干扰消除(PIC)技术。考虑MAI、背景光(APD)噪声、热噪声和接收机噪声,详细分析了采用该PIC技术的OCDMA通信系统的性能。结果表明,基于组信息的PIC技术,可以有效地消除采用MPC/OOC作为地址码的OCDMA通信系统的MAI,提高该系统的系统容量和误码率性能。In order to reduce the effect of ance of optical code division multiplexing multi-access interference（MAI） on the performaccess（OODMA） communication systems,a new kind of parallel interference cancellation（PIC） technology based on group information used in two dimensional OCDMA communication systems with MPC/OOC is presented. Considering the effects of MAI ,avalanche potodiode（APD） noise,and thermal noise, the performance of this proposed OCDMA communication systems with MPC/OOC is analyzed in detail. The results show that this proposed PIC technology with group information can effectively reduce the MAI,and when the received optical power is lager enough,the MAI in the two-dimensional OCDMA communication svstems can be reduced completely.
