antenna design chapter 5

说明：  自己编写的计算光流场的MATLAB程序，基于梯度的方法，非常简单(I have written a MATLAB calculation of optical flow procedures, based on the gradient method and it is very simple)

时频分析matlab工具箱,这是TFTB的指导使用书籍(Time-Frequency toolbox matlab)

设计一个阻带下限0.45*pi 阻带上限0.8*pi 通带下限0.55*pi 阻带上限0.7*pi 通带衰减0.15dB，阻带衰减40dB，分别用汉宁窗汉明窗凯瑟窗布莱克曼窗设计滤波器，对比分析各方法优劣(Design a stop-band limit 0.45* pi stopband limit 0.8* pi Passband lower limit 0.55* pi stopband limit 0.7* pi Passband attenuation 0.15dB, stop-band attenuation of 40dB, respectively Hanning Hamming window Kaiser window Blackman window filter design, comparative analysis of the pros and cons of each method)

二维绘图—MATLAB(有关matlab绘图的各种基本知识，实用)(2 d graphics- MATLAB)

这个文件实现了Matlab/Simulink中的三维查找表，对要用到查表的人有帮助，里面用到Reshape函数(This file implements the Matlab/Simulink in a three-dimensional look-up table for use to help people look-up table, which used Reshape function)

system view 实例模型包含数字调制QPSK,QAM.RICE衰落信道的仿真 数字频率合成器 线性移位寄存器 等等(system view instance of the model consists of digital modulation QPSK, QAM.RICE fading channel simulation of digital frequency synthesizer linear shift register, etc.)

用simlink开发的space-time coding仿真模型,仿真的精度与效率有不小的提高(with simlink development of the space-time coding model, Simulation accuracy and efficiency are not a small increase)

利用Matlab实现四波入射光子晶体波导(Using Matlab to simulate a four-wave incident photon crystal waveguide)
