Modulation and demodulation ASK. At the beginning, we create the digital signa (1 and 0), after we do the modulation, add noise and demodulation. At the end we do the reconstruction of the signal.

说明：  matlab常用函数参考，比较有用，尤其是对于使用matlab还不太熟练的编程人员。(matlab common function reference, more useful, especially for the use of matlab not very skilled programmer.)

power_Transfo3phCoreType_iexc.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_Transfo3phCoreType_iexc.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

相控阵天线的方向图（切比雪夫加权），与理论分析结果相比，小波包分析提取振动信号中的特征频率。( Phased array antenna pattern (Chebyshev weights), Compared with the results of theoretical analysis, Wavelet packet analysis to extract vibration signal characteristic frequency.)

用DSM调制1-bit输出，经简单模拟滤波电路，产生VGA控制电压。对于内部频率高、但VGA变化速度较慢的场合，可以达到很高的控制精度，从而省却了内部高精度DAC的模块(DSM modulation with 1-bit output, through a simple analog filter circuit, producing VGA control voltage. in the circumstance of high internal frequency, but need a slower changing VGA control, this program can achieve high control precision, and thus save the internal high-accuracy DAC module)

在matlab编译环境下对用户界面的编译快速入门教程，对于matlab初学者比较有帮助。(In the matlab compiler environment of the user interface compiler Quick Start Guide, more helpful for matlab beginners.)

基于MATLAB经典维纳滤波算法的仿真和矩阵构建(Classic Wiener filtering algorithm based on MATLAB simulation and matrix building)

This project consists of two back to back pwm converters used for simulation of traction load in normal operating mode. The first side is connected to a single phase network and uses hysteresis current control. The second side is connected to a three phase network and uses space vector modulation for controlling its inverter.

基于prony算法进行电力系统的低频振荡识别，可直接运行。(Prony algorithm based on low frequency oscillation recognition of the power system can be run directly.)
