nonlinear_draw

BP算法程序，通过此程序可以很好的对两类模式进行分离。效果明显。(BP algorithm program can be very good through this process to separate two kinds of models. Effect is obvious.)

distributed generation inverter

说明：  实现语音信号的分帧，也可以对其他信号进行分帧(Sub-frames of voice signals, other signals can also be sub-frame)

实现Pisarenko谐波分解法、MUSIC、基本ESPRIT、LS-ESPRIT、TLS-ESPRIT五种频率估计算法，并运用之对一个正弦波叠加噪声的信号源进行频率估计。(Use methods of Pisarenko, MUSIC, ESPRIT, LS-ESPRIT and TLS-ESPRIT to do frequency uation of one signal, which is composed of 3 sine waves and 1 white noise.)

说明：  做地震数据处理的去噪程序，通过原始信号，加噪声的信号，以及小波变换的信号进行比较分析，并生成图像。(Do the denoising program of seismic data processing, compare and analyze the original signal, noise signal and wavelet transform signal, and generate the image.)

利用MATLAB实现的图像的特征匹配，对于图像拼接和全景图像生成至关重要(MATLAB implementation of the image using the feature matching, image stitching for panoramic images and to generate essential)

说明：  前半部分仿真可能是对的 ，但是后面求频偏估计均方误差与定时估计均方误差的图像时，就不对了。希望告诉们能给我解答一下(code about OFDM)

基于子空间的盲信道估计算法，用的是奇异值的分解(Subspace-based blind channel estimation algorithm, using a singular value decomposition)

主成分分析是把多个指标化为少数几个终合指标的一种统计分析方法。本源代码为matlab中源代码，并添加了相应的分析注解(Principal Component Analysis is more than a few indicators as a final indicator of a statistical analysis method. Source code for which the source code Matlab, and add the corresponding analysis notes)

其中包括3个c++搜索源程序和2个matlab编写的fdtd程序(including three c search source and two Matlab procedures prepared by the fdtd)
