ACO_feature_selection

关于QPSK调制方法的一个小的仿真，使用matlab做的(QPSK modulation method on a small simulation, using matlab to do)

说明：  matlab环境中一些应用于图像处理的命令(matlab environment, some of the commands used in image processing)

这个程序是关于数字图像处理里面的测量物体周长，还有中心，最后是画出物体的最小外接矩形。(This program is about digital image processing measurement of body inside the perimeter, there are centers, and finally draw the object' s minimum bounding rectangle.)

the spectrum of the OFDM symbols in time domain

一个无刷直流电机模型及其PIC控制算法模型，可以实际使用。(A brushless DC motor model and PIC model control algorithm can be actually used.)

第一个是path 和 CLASSPATH的问题 第二个是package和import问题 第三个是public，protected，private，static，什 么时候用，为什么要用，怎么用 第四个是制作jar文件 (article is a path CLASSPATH issues and the second is The need to package and ort third issue is public, protected, private, static, and when used, why choose, how are with the fourth production jar files)

matlab实现信号分类，根据信号的相关性，获取信号类别，自动进行信号分类(matlab realize signal classification, in accordance with the correlation signal to obtain the signal type, automatic signal classification)

说明：  matlab的书 其中有论文等有一个例子希望新手喜欢(matlab book has essays which have an example of hope novice like)

Bit Error Rate for BPSK Modulation in Rayleigh Channel

关于雷达系统仿真和分析，完整代码，值得学习(On the radar system simulation and analysis, the complete code, it is worth learning)
