数字信号的传输：1、实现滚降系数分别为0，0.5，1时信号时域频域和功率谱密度以及眼图的波形，并比较异同。 2、对(2/4/8)PSK,DPSK通信系统进行蒙特卡罗仿真，通过功率谱密度、误比特率来比较他们的性能(采用最佳接收方式)。 (Digital signal transmission: 1, to achieve roll-off coefficients were 0,0.5,1 time domain when the signal frequency and power spectral density, as well as eye-diagram of the waveform, and compare the similarities and differences. 2, (2/4/8) PSK, DPSK communication system, Monte Carlo simulation, through the power spectral density, bit error rate to compare their performance (to adopt the best way to receive).)

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)
