Mathematic model of acoustic field for ultrasonic transducers according to "Ultrasonic beam structures in fluid media" paper

这是一篇分析了几类非高斯噪音模型的文章，对每种模型都进行了细致的分析(This is an analysis of several kinds of non Gauss noise model of the article, for each model are analyzed in detail )

说明：  4096阶QAM调制解调 matlab仿真(matlab 4096 QAM modulation)

速度非常块，效果接近blsgsm。堪称去噪的又一突破。 OWT SURE-LET SOFTWARE FOR MATLAB ******************************** Florian Luisier, Thierry Blu and Michael Unser Biomedical Imaging group Swiss Federal Institute of Technology Lausanne (EPFL), Switzerland. March 2007 This software implements the algorithm described in: [1] F. Luisier, T. Blu, M. Unser, "A New SURE Approach to Image Denoising: Interscale Orthonormal Wavelet Thresholding," IEEE Transactions on Image Processing, vol. 16, no. 3, pp. 593-606, March 2007. (Very block, the effect close to blsgsm. Denoising can be another breakthrough.

全国研究生数学建模大赛，PM2.5问题。采用灰色理论GM(1，1)模型实现地区PM2.5的预测，内含真实数据文件。(The Graduate School of mathematical modeling contest, PM2.5 problem. By using the grey theory GM (1, 1) model to realize the prediction of area PM2.5, with real data file.)

一维粒子滤波算法先建立状态模型和量测模型，再构造粒子滤波函数，通过统计分析得到估计后的状态变量，就是该算法的基本原理(One-dimensional particle filter algorithm to first establish a state model and measurement model, and then construct the particle filter function to be estimated by statistical analysis after the state variables, that is the basic principle of the algorithm )

SVM with K-fold cross validation

rt如题目说是，就是他的一个多元计算的案例的一套程序(topics such as rt said yes, he is a multi-case calculation of a set of procedures)

利用prony算法提取信号的幅值、频率和衰减因子，删除了mathworks工具包中的bug(The Prony algorithm is used to extract the amplitude, frequency and attenuation factor of the signal, and the bugs in the MathWorks toolkit are deleted.)

超宽带通信的仿真源程序，应该比较好使，请试一试(Simulation of ultra-wideband communications source, should be more so, please try)
