一个好用的信号特征提取、信号消噪代码

在matlab下有关s函数的应用，自抗扰控制器的S-function(S function in matlab under the application of Auto-Disturbance Rejection Controller S-function)

常规DOA谱估计music算法在多径环境下失效，SVD算法利用最大特征值对应的特征矢量重新构造奇异值矩阵，可以成功估计相干信号。(Conventional music spectrum estimation algorithm for DOA in multipath environment, failure, SVD algorithm using the maximum eigenvalue of the feature vector corresponding to re-construct singular value matrix, can be successfully estimated coherent signal.)

CWT (Continuous Wavelet Transform). It can resolve seismic data and detect hydrocarbon directly. We may set it in a single frequency to visualize current frequency of stratigraphy

说明：  一个功率谱估计的程序，有需要的可以研究一下(A power spectrum estimation program can be studied if necessary.)

程序对瑞利和莱斯信道进行了仿真，采用了经典的JAKES模型来建模，得到了瑞利和莱斯信道的随机变量的概率密度函数（pdf），分析了理论结果与仿真结果的差别。
