采用牛顿拉夫逊法计算电网的潮流，各节点电压，各支路电流。(Newton Raphson power flow calculation, and each node voltage current in each branch.)

对接收信号进行转化和功率谱分析。得到信号的统计特性，主要是噪声放面。(The received signal is transformed and the power spectrum analysis. Get the statistics of the signal, is mainly the noise area.)

Matlab 与 VPI 联合仿真的QPSK程序(Matlab simulation with VPI joint program of QPSK)

说明：  建立了预瞄侧向加速度驾驶员模型，依据驾驶员模型可以实现对不同道路的循迹行驶。(A forward-looking lateral acceleration driver model is established. According to the driver model, track driving on different roads can be realized.)

Simulated annealing (SA) is a generic probabilistic metaheuristic for the global optimization problem of applied mathematics, namely locating a good approximation to the global optimum of a given function in a large search space. It is often used when the search space is discrete (e.g., all tours that visit a given set of cities). For certain problems, simulated annealing may be more effective than exhaustive enumeration — provided that the goal is merely to find an acceptably good solution in a fixed amount of time, rather than the best possible solution.

说明：  通过不同大小的窗口移动，计算每个窗口内地形剖面数据的均方根值，得到的数据在双对数图中拟合直线可求得分维数(move the windows of different size and calculate the rms of the data in the window.Then using the resultant data to plot,so that the fractal dimension can be gotten.)

学习曲线拟合过程中肯定会遇到的问题，我总结了一下，希望有用。(The process of learning curve will certainly be problems, I summed up what I hope helpful.)
