POLYPHASE

基于MATLAB的扩频通信系统仿真研究,里面说明了扩频通信系统如何仿真(MATLAB-based spread-spectrum communications system simulation studies, which shows a spread spectrum communications system simulation how)

FDTD wave propagation program

Surfer是地学中常用的一个软件，可以完成等值线图，立体图，流向图等的汇制。其自带的类VBA的开发语言，可以进行二次开发。附件是一些源程序。其中的Jackknifes可以用来对比不同的内差方法，从而得出最优化的内差方法。 (Surfer is the study of a commonly used software, complete contour map, a three-dimensional map, map the flow of the system. Its built-in categories VBA programming languages that can be re-developed. Annex some source. Jackknifes which can be used for comparison within the poor, so as to come up with the most optimal way worse.)

本程序应用了混沌序列作为伪码生成器对直接扩频系统进行了仿真，并在多用户情况下作了仿真(the application procedures as a chaotic sequence of pseudo-code generator directly to the spread spectrum system simulation, Multi-user and the circumstances made Simulation)

说明：  使用matalab语言应用PLS算法对近红外光谱进行回归。(PLS algorithm is used to regress near infrared spectrum with MATALAB language)

添加高斯白噪声子程序 内容虽然很简单，但是很有用哦(Add white Gaussian noise subroutine)

一个简单的调用matlab DWT函数进行离散小波变换的示例程序(A simple function call matlab DWT DWT sample program)

对二维图像进行ROI提取的程序，提供GUI界面(A GUI to find ROI in 2D image)

说明：  matlab教程随书附赠教学源码 代码每句都有使用说明 谢谢下载(the source code affillate to a matlab book ,which is very useful!)

产生2ASK、4ASK、8ASK的m文件和产生的mat格式的数据文件。(Generated 2ASK, 4ASK, 8ASK of m documents and produced mat format data files.)
