33节点的配电网潮流计算程序，程序自带33节点数据(33 nodes in the power flow calculation program, the program comes with 33 node data)

说明：  关于用MATLAB设计对信号进行频谱分析和滤波处理的程序。(With regard to design using MATLAB signal processing spectral analysis and filtering procedures.)

matlab code for envelope detector for analog communications.

一个用在simlink 中用 dsp builder建立的FIR滤波器，每个波形都有波形显示，是学习DSP builder和FIR滤波器好资料。(One used in the FIR filter using dsp builder simlink established, each waveform has a waveform display, learning DSP builder and FIR filter good information.)

this is can apply to run simulink

采用bp神经网络对函数y=sin（x）进行训练，然后用测试集对训练的函数进行测试，也就是函数逼近sin（x)的曲线(Bp neural network using the function y = sin (x) for training, and then use the test set to test the training function, that is, function approximation sin (x) curve)

I,Q通道的 噪声过程是高斯的的,而且是互不相关的,他的功率谱也是白的. 因为I和Q通道的噪声过程是高斯的,而且是互不相关的 我们可以得到他们是相互独立(Papoulis,1984). 最后,由于I和Q通道是独立的零均值高斯过程,因此可以推导出:复信号:I+jQ,幅度是瑞丽分布的,幅度的平放是指数分布的,相位角arctan(Q/I)是在(0,2π]上均匀分布(I Q Gaussian noise)

关于图像的均衡化，绘制图像的灰度直方图，得到均衡化以后的图像(Equalization on the image and draw the image histogram, image obtained after equalization)

运用MATLAB实验环境设计了一个CDMA2000基站发射机的模拟(Experimental use of MATLAB environment designed a CDMA2000 base station transmitters Analog)

适用于AR模型的功率谱估计，包括基于Yule-Walker方法估计序列功率谱以及基于最大熵方法的功率谱估计。(AR model for power spectrum estimation, including methods based on Yule-Walker power spectrum estimation sequence and the method based on maximum entropy power spectrum estimation. )
