BPSK modulation with BER with and without OFDM Here are the files for a OFDM modulation. Where in I have used a BPSK modulation and showed the decrease in BER with OFDM. This project was done as a course project under the Guidance of Dr. Dayalan Kasilingam, Umass Dartmouth. (BER with BPSK modulation with and without O FDM Here are the files for a OFDM modulation. Whe 're in I have used a BPSK modulation and showed the decrease in BER with OFDM. This project was done as a course project under the Guidance of Dr.. Day alan Kasilingam, UMassOnline Dartmouth.)

FDTD一维场的叠加显示，对初学者有很大的帮助。(Superposition of one-dimensional FDTD field shows a great help for beginners.)

一个很好用现代智能优化算法，蚁群聚类优化算法的实现过程，实现结果很好(Ant cluster implementation of algorithm is kind, nice algorithm is a very good modern intelligent optimization algorithm, ant cluster of process to realize the optimization algorithm, realize the result is good)

用matlab4、5阶龙格-库塔法函数求解模拟批次试验动力学，(With matlab4 order Runge- Kutta method function solving analog batch tests dynamics,)

 The basics of digital images.  The use of MATLAB Image Processing Toolbox.  The basic operations on images.

m-file调查高功率放大器的影响，channelnoise在ofdm信号，当时介绍卡由于一个paprreductionmethod减少hpa效果。 (m-file investigation of high-power amplifier, channelnoise in ofdm signal, when introduced to reduce card due to a paprreductionmethod hpa effects.)

其实popupwindow用起来比Dialog 方便，因为dialog一切都需要你自己来实现，而popupwindow帮我们实现了很多，我认为在使用的时候关键我们要看清参数： popupWindow.showAtLocation(parent, gravity, x, y) parent这个是一个父view试图， gravity 这个默认是居中，我们要指定显示方式：Gravity.LEFT | Gravity.TOP 最后两个参数就是显示的坐标位置，这样就可以根据需求自己定位显示位置了

介绍关于MATLAB的一些函数基本命令以及常用的处理图像方法(Introduced the MATLAB function basic commands as well as the commonly used image processing method)
