数据的统计描述与分析的matlab实现与分析(Statistical description and analysis matlab realize and Analysis)

邻域平均法滤波 原图像画面清晰，添加勒椒盐噪声后图像上产生勒明显的黑色斑点（噪声），用不同模板的平滑滤波处理后图像上的噪声消失，但是图像变得模糊，并且，使用的模板越大，对图像的去噪效果越好，同时图像也变得越模糊。 (Neighborhood averaging filter clear picture of the original image, add the Le Salt and pepper noise generated after the image Roming noticeable black spots (noise), smoothing with different template processed image noise disappear, but the images become blurred, and the use of template bigger the better the image de-noising the same time, the image becomes more blurred.)

说明：  任意阵列输出数据的协方差进行奇异值分解，求出特征值和特征向量，利用信号子空间和噪声子空间的正交性，构造空间谱函数(Arbitrary array output data covariance singular value decomposition, eigenvalues and eigenvectors obtained using the signal subspace and noise subspace orthogonality spectral function space constructor)

说明：  利用Matlab/simulink搭建纯电动汽车底盘模型，仿真其底盘控制性能。(Using Matlab / Simulink to build a pure electric vehicle chassis model and simulate its chassis control performance.)

瑞利衰落信道条件下的MATLAB程序，是值得参考的程序(Rayleigh fading channels under the MATLAB program, the program is worth considering)

一个地震正演程序,matlab源码,对相关专业的初学者有帮助。(a seismic forward procedures, Matlab source of relevant professional help beginners.)

多种码的解码程序，用matlab写成，包含多种算法(A variety of code decoding process, written with matlab)

建立单频矩形脉冲信号,时间反转镜仿真,计算信号时反过后的能量增益(Establishment of single-frequency rectangular pulse signal, the time reversal mirror simulation, after calculating signal energy gain against)

维纳滤波语音增强算法:语音增强算法的维纳滤波器，通过scalart 1996提出的实现。使用一个决策指导的方法跟踪的先验信噪比。请注意，该信号的第一0.25sec用于模型的噪声，即，它是假定的演讲之后，0.25sec开始(Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec)
