时变通信系统的仿真，使两个例子的代码其所选信道为全同获平信道(Time-varying communication system simulation, so that two examples of the code of its selected channel with the agreed level for the whole channel)

很实用的在matlab环境下的图像处理源程序代码(matlab image processing under)

matlab数据插值与函数逼近.内容非常详尽的幻灯片。(matlab data interpolation and approximation. the content is very detailed slide show.)

msk调制，希望大家好好学习，天天向上，努力提高自己(msk modulation, I hope you study hard, every day, strive to improve their)

This code demomstrates an improved algorithm based on the local binary fitting (LBF) model in Chunming Li et al s paper: "Minimization of Region-Scalable Fitting Energy for Image Segmentation", IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008. Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows. Run the Demos in the M-files for several test images. Once an image comes out, click the mouse to generate a polygon as the initial contour: left click to get a number of points, then right click to get the end point. The number of iterations may need to be increased if the initial contour is too far away from the desired object boundary.

该程序实现二维的FFT变换，可以对图像做FFT变换，运行速度还可以。(procedures to achieve the two-dimensional FFT transform, the image can be done FFT, can also speed.)

L=31的Glod序列生成程序(the sequence generation process Glod)

说明：  本程序在c平台下开发，描述了awng信道下QPSK调制的方针。结果较为理想(The program developed in c platform described awng channel QPSK modulation approach. More satisfactory results)

光纤陀螺仪的光学器件偏振特性测试方法研究，惯性导航与光器件方面可用(fiber optical gyroscope devices polarization characteristics testing method, inertial navigation and the available optical devices)

对于高程数据的处理，通常需要各种格式之间的转换，此程序是将usgs高程数据转为dem格式的数据。(For the treatment of elevation data, usually need to convert between various formats, this program is the USGS elevation data to DEM format data. )
