OFDN调制的Matlab实现，根据802.11协议的OFDM特性编写(Matlab OFDN modulation, according to the properties of OFDM 802.11 protocol)

利用MATLAB中的GUI（图形用户界面），实现图像的灰度化，直方图，图像的错切变换，直方图均衡化，量化图像及图像的傅里叶频谱，是效果更加明显。(In MATLAB GUI (graphical user interface), to achieve graying, histogram, image conversion cut the wrong image, histogram equalization, quantized image and the image of the Fourier spectrum of the effect is more obvious.)

说明：  LMS/F组合算法由Shao-jen Lin和J.G.Jarris提出，它计算量增加不多却同时兼有LMS和LMF算法的优点。即收敛速度和稳态性能比基本LMS算法好，稳定性比LMF算法好。(LMS/F combination algorithm by the Shao-jen Lin, and JGJarris proposed, it is increasing much more calculations with both LMS and the LMF of the method. Ie, the convergence speed and steady-state performance better than the basic LMS algorithm, stability, better than the LMF algorithm.)

用MATLAB编写的一个猜数字游戏 就是随机生成4位数，你要在有限的步数内猜出。 用法：输入4位数字后按’ok’键，可看到当前结果。 按answer键查看正确答案 按reset键重新开始 还有很多不成熟的地方，发上来想和大家一起商量商量 主要问题： 1、步数限制功能没有完成 2、应当在显示区保留显示以前的所有步骤，但目前只能显示当前步骤 3、按键次数没有保留，无法判断你已经猜了几次 一个小bug：若输入3位数，则会自动把第一位置0 (MATLAB prepared with a game猜数字is randomly generated 4-digit, you have to step in with a limited guess. Usage: Enter the 4 digits after ' ok' button, the current results can be seen. By the answer key to view the correct answer by the reset button to restart where there are many immature, made up and we would like to discuss the main issues discussed with: 1, step 2 did not complete the functional limitations, it should be retained in the display shows all the steps before , but currently only shows the current step 3, the number keys will not be retained to determine a number of you have guessed a small bug: if the input 3-digit, it will automatically position the first 0)
