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

好用地 matlab 区域增长算法,先输入比较范围,再输入种子点数目,然后就是手动选取种子点了 ,好运哦!(good land Matlab regional growth algorithm, importing more scope to import seed spots, Then, they manually select seed, good luck!)

说明: K-MEANS算法是输入聚类个数k,以及包含 n个数据对象的数据库,输出满足方差最小标准的k个聚类。
(K-MEANS algorithm is the input number of clusters k, and n a data object that contains the database and output to meet the standard minimum variance k-clustering.)
