通过此代码，实现OFDM调制。设定子载波个数为6，每个信道的比特数是4000(OFDM MODULATION)

matlab入门到精髓，很好的资料，学习matlab不可缺少的哦。(matlab entry to the essence of good information, learning matlab Oh indispensable.)

本程序主要实现WIMAX总CTC编码解码功能，采用MATLAB语言(This procedure achieved total CTC codec WIMAX functionality, using MATLAB language)

说明：  CFAR代码，CFAR是用于雷达的一种滤波方法，称为平均值滤波，本程序给出了主程序以及CFAR-function，并且有噪音图和信号图，可以进行比较分析(CFAR code, CFAR radar for a filtering method, known as average filtering, the process is the main program and CFAR-function, and the noise and signal map plan, it can conduct a comparative analysis)

Generate a random sample of size n a finite mixture estimate of the Old Faithful Geyser data

产生右图所示图像f1(m,n)，其中图像大小为256×256，中间亮条为128 ×32，暗处=0，亮处=100。对其进行FFT： ① 同屏显示原图f1(m,n)和FFT(f1)的幅度谱图； ② 若令f2(m,n)=（-1）m+n f1(m,n)，重复以上过程，比较二者幅度 谱的异同，简述理由； ③ 若将f2(m,n)顺时针旋转90 度得到f3(m,n)，试显示FFT(f3)的幅 度谱，并与FFT(f2)的幅度谱进行比较； ④ 若将f1(m,n) 顺时针旋转90 度得到f4(m,n)，令f5(m,n)=f1(m,n)+f4(m,n)，试显 示FFT(f5)的幅度谱，并指出其与FFT(f1)和FFT(f4)的关系； ⑤ 若令f6(m,n)=f2(m,n)+f3(m,n)，试显示FFT(f6)的幅度谱，并指出其与FFT(f2)和 FFT(f3)的关系，比较FFT(f6)和FFT(f5)的幅度谱。(Generating an image f1 (m, n) shown in the figure, wherein the image size is 256 256, the intermediate light bar 128 32 0 = dark, bright Department 100. Its FFT: ① screen display picture f1 (m, n) and the FFT (f1) of the amplitude spectrum ② If so f2 (m, n) = (-1) m+n f1 (m, n), repeat The above process, comparing the amplitude spectrum of the similarities and differences between the two, brief reasons ③ If f2 (m, n) 90 degrees clockwise to get f3 (m, n), try to display FFT (f3) the amplitude spectrum and with the FFT (f2) comparing the amplitude spectrum ④ If f1 (m, n) obtained by 90 degrees clockwise f4 (m, n), so f5 (m, n) = f1 (m, n)+f4 (m, n ), try to display FFT (f5) amplitude spectrum, and pointed out its relationship with the FFT (f1) and FFT (f4) of ⑤ If so f6 (m, n) = f2 (m, n)+f3 (m, n) and try to display the FFT (f6) amplitude spectrum, and pointed out its relationship with the FFT (f2) and FFT (f3), comparing FFT (f6) and FFT (f5) amplitude spectrum.)

说明：  SURF算法，是SIFT的升级版，速度更快，性能也不差，快速实现图像特征点的检测和匹配。(SURF algorithm, is an upgraded version of SIFT, faster, not bad performance, rapid detection of image feature points and matching.)
