新型改进光双二进制传输的编解码方案
提出了改进型光双二进制信号在高速率(≥10Gbit/s)传输时预编码的一种新方案。通过分析编解码过
程,证明该信号传输时不易受码间干扰影响,能用二进制强度调制一直接检测的系统接收信号。仿真产生了该信
号的2种码型。结果表明,采用色散补偿技术能使MD NRZ和MD.RZ信号在长距离传输后克服眼图失真,MD-RZ
信号比MD.NRZ信号在传输后有更低的误码率。(Abstract:Anovel pre-coding schemeformodified optical duobinary signalswasproposed.It couldbe applied to缸ansmit
