WiMAX Physical layer simulator in Matlab

实现24位RGB彩色图像，先转化为灰度图像，而后用大津法实现二值化，并显示阀值。(To achieve 24-bit RGB color images, the first converted to grayscale images, then using Otsu binarization method to achieve and display threshold.)

使用matlab来处理常见的线性规划问题，附有pps的说明(matlab handle common linear programming problem)

this is a source code of beamforming

this code calculate how use this programmation

彻底解决Matlab 2008b 及以上版本Simulink 无法直接打开或无法保存含中文字符MDL文件的错误(Completely resolved Matlab 2008b and above Simulink unable to directly open or save a file containing Chinese characters MDL error)

梯度下降法是一个最优化算法，常用于机器学习和人工智能当中用来递归性地逼近最小偏差模型(The gradient descent method is an optimization algorithm used in machine learning and artificial intelligence to recursive approximation of the minimum deviation model )

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)
