assignment-6

说明：  OFDM系统是将一个用户的信息分别调制在了多个相互正交的子载波上面，对频率偏移非常敏感，OFDM同步技术非常关键，这里予以实现(OFDM system is a user' s information were prepared in a number of mutually orthogonal subcarriers above, is very sensitive to frequency offset, OFDM synchronization is critical to achieve here)

matlab需要那么复杂的多重积分,实在没办法才考虑使用.一般来说,积分中带有参数,无论是被积表达式或者说积分限都是相当麻烦的,求解消耗的时间非常多.............数值积分才是解决问题的通法,可以自己调节精度~(it is good. If you visited Indianapolis you would be able to find your way around easily because most of the streets corss each other like a chessboard(棋盘). In the center of the city, called the Circle, stands the Soldiers and Sailors’Monument, 100 Meters high. Also in the center there are many buildings made of the famous Indiana stone, which makes them white in color.)

模式分类（杜达）（第二版）电子书 及原书中的代码。绝对值得永久收藏。(Pattern Classification (Duda) (second edition) book, e-books and the original code. Definitely worth the permanent collection.)

对鱼眼图像进行矫正，matlab程序供大家参考(Fish-eye image correction, matlab program for your reference)

非均匀傅里叶变换，此程序仿真了非均匀采样信号的非均匀傅里叶变换(Non-uniform Fourier transform, this non-uniform Fourier transform of a non-uniform sampling signal simulation program)

Project Report A 5.2 GHz Differential Cascode Low Noise Amplifier

这是一个基于PR控制的单相逆变器，实现对交流量的无静差跟踪(This is based on a single-phase inverter PR control, realize no static difference to cross flow)

说明：  滤掉低频段和高频段频率，分波段滤波，过滤掉噪声干扰，绘制功率谱密度曲线(Filter out the low and high frequency bands, filter in different bands, filter out the noise interference, and draw the power spectral density curve.)

说明：  陈毅将军的生平传记，深刻描述了陈毅将军生活中的点点滴滴(Of General Chen Yi biographies of General Chen Yi-depth description of life in bit by bit)

说明：  MATLAB的jsp和K聚类算法，试试看，不错的，谢谢(MATLAB' s jsp and K clustering algorithm, give it a try, yes, thank you)
