FFT2

OFDM基本原理仿真程序，本程序是基于IFFTFFT实现的OFDM系统仿真(The basic principles of OFDM simulation program, this program is implemented based on the OFDM system simulation IFFTFFT)

OFDM的LDPC编码调制程序，非常有用哦！经过学习，肯定可以掌握的！(The LDPC coded OFDM modulation process)

遗传算法的matlab代码，用起来还不错，欢迎下载使用，谢谢各位。(The matlab code of genetic algorithm is pretty good to use. Welcome to download and use. Thank you.)

用matlab编制的机器人求逆以及求时间的程序，个人感觉很有应用借鉴价值。(using Matlab based robot inverse time and the procedures for seeking personal feeling good application reference value.)

时间序列的预测及中间状态，包括误差检测以及其和中间状态的关系(representation of status)

说明：  背景差分法对运动汽车的检测，对检测得到的汽车图像进行预处理和边缘提取(Background difference method for the detection of movement of motor vehicles, the vehicle has been detected image pre-processing and edge extraction)

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )
