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 :较长的码字和短的初始脉冲有利于提高系统性能
Phase-encoding spread spectrum optical code division multiple access (OCDMA) communication system is one of the hot topics in OCDMA research.In recent years, a theoretical model of phase-encoding spread-spectrum OCDMA communication system using phase mask has been established and the system performance has been analyzed. Numerical results show : Longer codeword and short initial pulse improve system performance
