摘要 对于采用时间域编码的光码分复用 (OCDMA)系统而言 ,多址干扰 (OMAl)问题是严重影响系统误码率和同时用户数的主要原因。针对引起强度调制 /直接检测 (IM/DD)光通信系统 OMAI的原因 ,讨论了通过改良码系和检测技术来改善系统性能的方法 ,提出了多脉冲检测方案 ;通过扩展到光域的 Shannon公式 ,简要讨论了时间域以外的编码方法并分析了可能存在的问题 ,提出并讨论了一种通过时分 /波分相结合利用 M系列码的方案 ,指出这种通过码系数学变换在时间域利用电域成熟码系的编码方案是目前解决 This paper discusses the limitations of coding for OCDMA in time domain and how to break through of them,points out the OMAI is the pricncipal cause of influencing system BER and simultaneousness mumber of subscriber.In IM/DD optical communication system,be directed against the causation of OMAI,this paper discusses the method of improving system performance via refine code series and detection technology,and puts forward multi pulse detector;The method of Shannon formula and other coding method out of time domain is proposed with a example of WDM/OCDMA system for m sequences.
