对文献《Simulation Models With Correct Statistical Properties for Rayleigh Fading Channels》提出的Rayleigh信道模型的仿真，仿真了信道的自相关，互相关，以及四阶统计量。仿真结果与文献一致。目前PDF的仿真的效果不好，还未奉上。关于LCR,AFD也没有做。但是总体说来，目前的仿真结果与文献是完全符合的。对应的文献也放到压缩包了。(This matlab code for paper, <Simulation Models With Correct Statistical Properties for Rayleigh Fading Channels>.This papar is very popular in channel estimation simulation.The paper is also upload with the code.)

一个很好的MATLAB源代码——OMP，OMP算法的改进之处在于：在分解的每一步对所选择的全部原子进行正交化处理，这使得在精度要求相同的情况下，OMP算法的收敛速度更快。(A good MATLAB source code-- OMP, OMP algorithm improvement lies in: every step of the decomposition of orthogonalization processing all of the selected atoms, which makes the accuracy requirement of the same circumstances, the OMP algorithm s convergence speed is faster. )

四维水质模型中污染浓度分布, 本程序运行需要几分钟时间； 2.两个M文件都放在MATLAB目录下； 3.在命令窗口中输入lianxuwuran(t)，回车即可运行，其中t为时间(The distribution of concentration of polluted water quality model in four )

使用MATLAB制作gui，有代码举例，有ppt说明(Produced using MATLAB gui, there is the code example, there ppt shows)

说明：  老师给的一个可以作为初学S变换的例程，是正确的(A teacher can serve as a beginner to the S-transform routines, is correct)

传统的短时谱估计语音增强算法通常假设语音谱分量相互独立，没有考虑语音谱分量间的相关性。针对这 一问题，该文提出一种新的基于多元Laplace分布模型的短时谱估计算法。首先，假设语音的离散余弦变换(DCT) 系数服从多元Laplace分布，以此利用谱分量间的相关性；在此基础上，利用多元随机矢量的高斯尺度混合模型表 示，推导得到语音DCT系数矢量的最小均方误差(MMSE)估计的解析表达式；并进一步推导了基于该分布模型的 语音存在概率，对最小均方误差估计子进行修正。实验结果表明，该算法在抑制背景噪声和减少语音失真等方面优 于传统的语音增强方法。(The spectral components of speech are usually assumed to be independent in traditional short-time spectrum estimation, which is not the case in practice. Tosolve this problem, a new speech enhancement algorithm with multivariate Laplace speech model is proposed in this paper. Firstly, the speech Discrete Cosine Transform (DCT) coefficients are modeled by a multivariate Laplace distribution, so the correlations between speech spectral components can be exploited. And then a Minimum-Mean-Square-Error (MMSE) estimator based on the proposed model is derived using a Gaussian scale mixture representation of random vectors. Furthermore, the speech presence uncertainty with the new model is derived to modify the MMSE estimator. Experimental results show that the developed method has better noise suppression performance and lower speech distortion compared to the traditional speech enhancement method. )
