UWB，超宽带信号分析必用的子函数，第15部分！(UWB, ultra-wideband signal analysis will be used for Functions, Part 15!)

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：  本程序用于实现求解并绘制正弦信号功率谱密度的功能(procedures used to achieve the solution and the mapping of sinusoidal signal power spectral density function)

蒙特卡罗实验，计算误码率。为书上的程序。可以参考(Monte Carlo experiment to calculate the error rate. Procedures for the book. Can refer to)

该M文件的编写将方波响应转化为脉冲响应的程序和将脉冲响应转化为方波。(The preparation of the M file into the square wave response procedures and the impulse response into a square wave pulse response.)

可以完成地震记录的合成，实现地震记录的正演模拟(Synthetic seismogram can be done to achieve forward modeling of seismic records)

基于差分进化的粒子群优化算法，（全局最优粒子群优化算法）(Based on differential evolution particle swarm optimization, (global optimization PSO))

此程序是matlab计算六层框架结构在地震作用下的动力响应，并绘出动力响应曲线(This program is matlab calculation of the dynamic response of the six-story frame structure under earthquake, and draw power response curve)

常用的一些图像处理Matlab源代码,比如数字图像的傅立叶变换，二维离散余弦变换的图像压缩，采用灰度变换的方法增强图像的对比度，直方图均匀化，图像滤波等(Some commonly used image processing Matlab source code, such as digital image Fourier transform two-dimensional discrete cosine transform image compression method using gray transform image contrast enhancement, histogram equalization, image filtering, etc.)

近年来发展的多线圈并行采集技术极大地缩短了扫描时间,敏感度编码(sensitivityencoding,SENSE)技术就是其中的代表,(In recent years the development of coil parallel sampling technology more greatly shorten the scanning time, sensitivity encoding (sensitivityencoding, SENSE) technology is one of the representative,)
