CGHbyFFT

本文主要叙述的是利用MATLAB软件实现图像的几何操作。利用imresize() imrotate() imcrop() 等函数实现图像的缩放，选转，剪切。 在对图像的几种几何操作中，图像的缩放和旋转都要用到插值操作。(This paper describes the use of MATLAB software images of geometric operations. Use imresize () imrotate () imcrop () Function Image Scaling , elected to the shear. In the image of several geometric operation, image scaling and rotation should be used interpolation operation.)

LDPC编译码仿真。部分迭代编码，不限定H矩阵类型，SPA算法译码。(LDPC codec algorithm in AWGN channel。)

说明：  TDOA算法，用于解决uwb中的matlab仿真定位问题。(TDOA algorithm is used to solve the MATLAB simulation positioning problem in uwb.)

将检测数据常用的.lvm格式读取到workspace的matlab程序(Load lvm files)

滤掉低频段和高频段频率，分波段滤波，过滤掉噪声干扰，绘制功率谱密度曲线(Filter out the low and high frequency bands, filter in different bands, filter out the noise interference, and draw the power spectral density curve.)

这是利用MATLAB做L-S谱分析的程序，主要用于功率谱分析，简单易懂(MATLAB to do this is to use spectral analysis of the LS procedure, mainly used for power spectral analysis, easy-to-read)

科学计算器的设计与编程，方便大家进行学习。(Design and programming of the scientific calculator, to facilitate learning.)

MATLAB GUI：GUI中的基本操作：简单的文本框数据传递 (MATLAB GUI: GUI in the basic operation: simple text box data transfer)

wavelet domain denoising-code小波图像去噪源代码，可以使用，能够运行出结果。(wavelet domain denoising)

说明：  1.这是一个递推极大似然算法代码; 2. 附一份PDF说明文件.(1.This is a recursive maximum likelihood mehod code; 2.There is the PDFfile.)
