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 high speed data mte signals(≥ 10Gbit／s)．Through analyzing the process of coding and decoding，It Was demonstrated thatmodified opticalduobinary sign alshave capabilityin reductionofpulse—to-pulseinteraction ， and couldbe di． recaymeasured through aconventionalbinaryintensitymodulationdirectdetection(IM—DD)receiver．Twomodified optical duobinary sign als’formats were simulated to generate．Sim ulation results show that MD．NRZ and MD-RZ signals’ formats Can avoid the eye diagrams’distortion for long—distance transmission，if the dispersion Can be compe nsated in each amplifier span．Moreover,theMD-RZ signalhaslowerBER than theIVID-NRZ signal afterlong-distance comm．unication．)

基于分水岭算法源程序含文章，可有效分割处图像(Based watershed algorithm source code containing the article, which can effectively split at the image)

安装cvx需要的license.dat文件和64位的CVX，，然后解压到安装的matlab文件中，打开matlab，然后路径选择cvx，在command windows中输入cvx_setup即可实现安装。(Cvx need to install license.dat file downloaded to cvx in, download the corresponding cvx, and then extract it to install matlab file, open matlab, then the path selection cvx, enter cvx_setup in command windows installation can be realized.)

说明：  使用基于栅格地图的Q-learning进行路径规划。(This program use Q-learning to path planning,based on grid map.)
