对输入的数字图像进行二维离散傅立叶变换，由matlab实现(The input digital image to two-dimensional Discrete Fourier Transform, from matlab realize)

PFC 的原理与分析设计 我们作比赛的资料(Principle and Analysis of PFC design we make the game data)

ICA-PCA 故障诊断，matlab源码。(ICA-PCA Fault diagnosis)

说明：  模型以永磁直驱同步发电机组为研究对象，对包括风力机、发电机及其控制系统等各部分进行控制建模与仿真，接着通过坐标变换，分析并网逆变器在d／q坐标系下的模型，采用基于d轴电网电压定向矢量控制，并通过前馈补偿，实现有功、无功的解藕独立控制.(The model takes the permanent magnet direct drive synchronous generator set as the research object, and carries on the control modeling and simulation to each part, including wind turbine, generator and its control system, and then analyzes the model of grid-connected inverter in d coordinate system through coordinate transformation. The voltage oriented vector control based on d-axis power network and feedforward compensation are adopted to realize the decoupling independent control of active and reactive power.)

用LSB算法做图片隐藏，提取及检测，适合初学者学习参考(LSB algorithm to do image extraction and detection of hidden)

该程序是一种子带的模糊函数程序，该程序主要是将宽带信号分成若干子带，然后每个子带做模糊函数，最后再合成(The program is a sub-band ambiguity function program, the main procedures is the broadband signal is divided into several sub-band, and then each sub-band fuzzy function, and finally resynthesis)

模拟了高斯白噪声通过IS-95基带脉冲成形FIR滤波器的过程。绘制了FIR滤波器的频响曲线，噪声输入前与输出后的波形与功率谱(Simulated Gaussian white noise through the IS-95 baseband pulse shaping FIR filter. Drawn FIR filter frequency response curve, noise input and output waveform and power spectrum)

说明：  网络编码利用ra加网络编码awgn信道 调制利用cpm调制可以快速运行方便理解(Network coding uses RA plus network coding AWGN channel modulation and CPM modulation to run quickly and understand easily)

相当好的matlab程序，对建模爱好者来说绝对是好东西(it is very good for everyong)

对于一般的二值图像，可以将图像中的符号提取出来。(For the average values of two images, the symbols can be extracted from the image.)
