摘要本文对基于步进啁啾光纤光栅编解码器的OCDMA系统性能进行了分析,通过数值模拟得到系统性能与系统参数满足的关系,为改善系统性能提供可靠的依据.本文是对基于步进啁啾光纤光栅的OCDMA 频阈相位编码一文的深化. The performance of optical code-division multiple-access （OCDMA） system with an encoder /decoder based on step chirped fiber bragg gratings （SCFBGs） is presented. In the system, the multiple access interference （MAI） is the main noise and the unsuccessfully decoded pulse is assumed to be a Gaussian random process. Simulation shows that longer code length and narrow pulse improve the performance of system. And when threshold is 0.7, the best bit error rate （BER） can be obtained for this OCDMA system.
