说明：  读取sgy格式数据，并利用wigb进行成图(Read sgy format data, and use wigb to map)

关于BP网络的设计及改进方案实现分类，包含matlab源程序(On the BP network to achieve improvement program design and classification, including source code matlab)

利用matlab 编程求解对流弥散方程，实现PDE函数的数值解法(Using MATLAB programming to solve convection dispersion equation, the numerical solution of PDE function is achieved)

小波阈值去噪的程序，实现对图像的去噪，也可以用于对简单的语音和其它信号(Wavelet threshold denoising procedures)

说明：  是ｍａｔｌａｂ相关的基础学习，在我们学校小学期的时候用到了(Matlab based learning in our school primary school period when used)

OMP算法的本质思想是：以贪婪迭代的方法选择D的列，使得在每次迭代的过程中所选择的列与当前冗余向量最大程度的相关，从原始信号向量中减去相关部分并反复迭代，只到迭代次数达到稀疏度K，停止迭代。(OMP compressed sensing )

simulink files for fsk modulation and demodulation

this file is QPSK using simulink..

these are fuction descriptions of different spectrum sensing methods

This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db
