FDTD仿真，点源为硬源，上半部分是玻璃，下半部分是空气，能观察得到电磁波的反射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor.)

Lorenz_MatlabCode,分形几何中提出的洛仑兹分形，生成图，matlab源代码(Lorenz_MatlabCode, fractal geometry of the Lorentz proposed fractal, generated map, matlab source code)

LTE协作通信系统的两种路由算法比较，AF和DF，里面有详细的仿真程序和结果图，是初学者的很好材料。(Comparison of two kinds of routing algorithm for LTE cooperative communication systems, AF and DF, there are detailed simulation procedures and results, is a good material for beginners.)

图像扫描的zigzag程序,可用于图像处理的水印程序，图像压缩等等(zigzag )

to find a losses in tranmission line

说明：   灰度处理，可以直接运行，matlab实现 ( matlab implementation)

扩频通信系统仿真 ——系统将基带信号（即信息）的频谱扩展至很宽的频带上，然后再进行传输，即将欲传输的信息数据用伪随机序列编码调制，实现频谱扩展，然后通过信道编码发送出去；接收端采用与发送端完全相同的伪随机序列作为本地解扩信号进行相关处理，以恢复信息，最后进行解调，完成整个系统的接收。(Simulation of spread spectrum communication system- the system baseband signal (ie, information) be extended to a wide spectrum of frequency bands, and then transferred, will want to use transmitted information data sequence of pseudo-random code modulation, to achieve expansion of the spectrum, and then sent channel coding receiver and transmitter use the same pseudo-random sequence as related to the local despreading signal processing, in order to restore the information, the final demodulation, the receiver to complete the system.)

光流法（Optical Flow）的Matlab实现(Optical flow method (Optical Flow) Matlab realize)

OFDM的关键技术和应用，非常非常好用的一本书(Key technologies and applications of OFDM, very, very easy to use book)
