摘要 该文主要考虑利用图像噪声再生技术来提取图像细节 其思想是利用被滤除的噪声信号进行回收再利用 通过对噪声信号和初步去噪信号进行小波变换 比较它们的小波系数 当噪声信号的小波系数达到一定的阈值时 将噪声信号的小波系数保留叠加至初步去噪信号的小波系数 然后利用传统的软阈值去噪的方法来进行图像的去噪 从而达到既能够去除噪声 又能保留图像细节的目的 实验证明 该方法较传统的方法在去噪和细节保持上有改进(Abstract In this paper, consider using images to extract the noise regeneration of its ideological image detail is the use of the noise signal was filtered to recycle through the noise signal and the initial wavelet transform de-noising signal comparison of their wavelet coefficients of the wavelet signal when the noise coefficient reaches a certain threshold will be the noise signal superimposed to the wavelet coefficients to retain the initial de-noising signal wavelet coefficients and then using the traditional soft-threshold denoising approach to image denoising in order to achieve the removal of noise can not only be able to retain The purpose of image detail that the methods of the experiment a more traditional approach to denoising and detail in there to keep improving)

该代码利用matlab，根据各类边界条件的设定，实现了FDTD的算法。( This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a three-dimensional Cartesian space lattice comprised of uniform cubic grid cells.)

几种实用的包含数据关联算法的matlab代码文件，内容中包含NN,PDA,JPDA及国际上较新的EM—KF算法的仿真程序，很实用(Several practical contains matlab code file of data correlation algorithm, NN are contained in the content, PDA, JPDA and relatively new in the world is EM- KF algorithm simulation program, very practical)

用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编解码全部自己编写代码(S-Function方式)(Simulink simulation using convolutional coding and Viterbi decoding method used to decode, which codec to prepare all their own code (S-Function mode))

对不同的查找精心效率的估计，其中采用了3中不同的查找 方式。(Search carefully for different efficiency estimates, which used 3 different search methods.)

用于检测两个信号的延时情况,应用方面非常广泛(for detecting signal delay, the application is very extensive)

g(x)=f(m,n,L), 其中,m,n,L均服从正态分布,分布情况也在所给的图中. 使用matlab,用蒙特卡罗模拟法 对该函数进行模拟,得出g(x)大于0的概率.(G (x) =f (m, N, L), of which, m, N, L are the normal distribution, distribution is also in the picture. The use of MATLAB, simulates the function by Monte Carlo method, the G (x) greater than 0 probability.)
