一个matlab实现bp的源文件，也许各位用得上，请大家多多指教(Bp realize a matlab source files, perhaps you useful, please everyone exhibitions)

这是我毕设做自动调焦仿真实验时，编写的自动调焦函数的Matlab代码，把基于灰度梯度的调焦函数都仿真了(This is what I do complete auto-focus based simulation experiments, the preparation of the automatic focusing function of the Matlab code, the gray gradient-based simulation of the focusing functions)

OFDM的matlab仿真，调制解调，交织，信道编解码，高斯信道和瑞利衰落信道下的分别进行仿真的程序。(OFDM matlab simulation, modulation and demodulation, interleaving, channel coding and decoding, Gaussian channel and Rayleigh fading channel simulation procedures, respectively.)

对bpsk信号进行调制，还可以对 qpsk ，16qam信号进行调制(For bpsk signal modulation, can also qpsk, 16qam signal modulation)

matlab矩阵的生成,希望对大家有好处~(matlab matrix formation, in the hope that everyone will benefit ~)

说明：  IIR滤波器设计 在设计一个IIR数字滤波器时，我们根据指标先写出模拟滤波器的公式，然后通过一定的变换，将模拟滤波器的公式转换成数字滤波器的公式(IIR filter design in the design of an IIR digital filter, we first write the analog filter based on index formula, and then through a certain transformation, the analog filters into digital filters equation formula)

vsp seismic inversion

小波，小波包去噪和分析相关的一些编程，供初学者学习之用(Wavelet, wavelet packet de-noising and analyze some programming related, for beginners learning to use)

STA LTA 长短视窗处理地震信号算法，绝对自己编的，有很好的效果(STA LTA length windows seismic signal processing algorithms, absolutely own, and have a good effect)

说明：  一种有效的滤波算法，通过比较特定区域内的像素点的邻域均值来进行图像的去噪滤波。(An effective filtering algorithm, by comparing the particular pixel within the region to the neighborhood mean filter for image denoising.)
