PPM　脉冲位置调制，Matlab 代码，它描述了PPM 技术在UWB 超宽带无线通信中的应用(PPM, Pulse Position Modulation in use of UWB.)

用一个双极性基带数据信号对载波进行角度调制产生BPSK信号s(t)=10cos[wct+Dpm(t)]。(With a bipolar baseband data signal generated BPSK modulated carrier signal point s (t) = 10cos [wct+ Dpm (t)].)

产生一个长为1000的二进制随机序列，“0”的概率为 0.8，”1”的概率为0.2；  对上述数据进行归零AMI编码，脉冲宽度为符号宽度 的50 ，波形采样率为符号率的8倍，画出前20个符 号对应的波形（同时给出前20位信源序列）  改用HDB3码，画出前20个符号对应的波形  改用密勒码，画出前20个符号对应的波形  分别对上述1000个符号的波形进行功率谱估计，画出 功率谱  改变信源“0”的概率，观察AMI码的功率谱变化情况 (Base band signal spectrum)

黑油模型数值模拟入门指南 市场上有不少关于油藏数值模拟的书，但好像没有类似围棋入门指南那样从基础开始一步 一步介绍的书。我收到不下二十个问油藏数值模拟如何入门的问题。我尝试写一写油藏数值模拟 入门指南，希望对那些刚刚开始进入油藏数值模拟领域的工作者有所帮助(Numerical simulation of black oil model Start Guide on the market, many of reservoir simulation, but it seems there is no similar entry guidelines go as the beginning of step by step from basic introductory book. I have received no less than 20 reservoir simulation asked how the issue of entry. I try to write to write a reservoir simulation Start Guide, I hope for those just beginning to enter the field of reservoir simulation will help workers)

用ukf实行滤波，然后比较真实值并进行比较(Implemented by ukf filter, and then compare the real value and compared)

在用MATLAB进行论文写作画图时，需要对图形部分放大，该函数效果很好。(It is used to magnify the plot figure in Matlab)
