摘　　要：相位编码扩谱光码分多址 (OCDMA)通信系统是近年来OCDMA研究的热点之一 .本文建立了采用相位掩模板的相位编码扩谱OCDMA通信系统理论模型 ,分析了系统性能 .数值结果表明Phase encode spreading optical code division multiplex access (OCDMA) communication system is one of the research focuses in recent years.We have established the system model of such OCDMA system basing on phase mask and analyzed its performance.The calculated result shows that longer code length and shorter initial optical pulse width will lead to better system performance.

关 键 词：相位编码扩谱 相位掩模 光码多分址 通信系统 性能分析
