注水定理，是移动通信原理里的，关于资源分配的基本算法。(water filling Power Allo)

对电力系统谐波进行了分析和仿真.仿真效果好,可以直接使用(The power system harmonics analysis and simulation. Simulation results, and can be used directly)

链码，最小包围核的matlab程序，数字图像处理(Chain code, minimum surrounded by nuclear matlab program, digital image processing)

这个例子显示了一个静止同步补偿器（STATCOM）用于中点电压调节的500千伏输电线路。(This example shows a Static Synchronous Compensator (STATCOM) used for midpoint voltage regulation on a 500-kV transmission line.)

Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence. a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}. b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before spreading and after spreading

一个关于matlab的教程，对于初学者来说是非常有用的(A tutorial on matlab for beginners is very useful)

回归算法，输出回归方程系数，平方和，剩余平方和等。(Regression algorithm, the output coefficient of the regression equation, sum of squares, residual sum of squares and so on.)

设模拟带通信号频率范围1KHz—1.1KHz，设计一个采样频率8KHz数字频谱分析系统，要求频率分辨率0.1Hz。若对信号直接用FFT进行频谱分析(simulation based communications, with the frequency range 1KHz- 1.1KHz. Design of an 8 KHz sampling frequency digital spectrum analysis system requirements frequency resolution 0.1 Hz. If the signal directly FFT spectrum analysis)

程序运用matlab语言，读取了电流数据，并对电流数据进行了经验模态分解，观察分解各层的特征(Program using matlab language, read the current data, and current data were empirical mode decomposition, the decomposition observed characteristics of the layers)
