高斯噪声的源程序

OFDM 系统信噪比估计，matlab源代码(OFDM system, SNR estimation, matlab source code)

说明：  精通matlab，很好的matlab 教材txt版本，适合电子书(Proficient in matlab, a very good txt version of matlab materials, suitable for e-books)

几种不同阈值去噪方法的程序仿真代码，可以很好的进行消噪。( kings of THR denoising)

程序对2发2收系统进行ZF算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端采用最大似然检测算法，仿真其误比特率特性。(The ZF algorithm simulation program 2 admission system. Send signals using QPSK modulation, channel prevail static Rayleigh flat fading channels, the introduction of noise with mean 0 Gaussian white noise, the receiving end using the maximum likelihood detection algorithm, simulation of the bit error rate characteristics.)

基于AR模型的Rayleigh瑞利衰落信道仿真源代码()

该代码是对人脸进行光照处理，先进行gamma变换，然后进行Dog双边滤波，然后进行灰度亮度的均衡。该方法能够有效提高光照变化的情况下的系统识别性能(The code is the human face of light treatment, the first for gamma conversion, and then Dog bilateral filtering, then the brightness of the gray balance. The method can effectively improve the illumination changes in the case of system identification performance)

复杂网络社团结构划分算法里最经典的ＧＮ算法和ＦＮ算法的实现原码(Community structure of complex networks division algorithm in the most classic GN algorithm and the algorithm to achieve the original code FN)

有约束最优化问题：利用matlab中已有的函数。举了一个利用里面函数求最小值的例子。这是最优化与运筹学中会经常遇到的问题(Constrained optimization problem: using the matlab existing function. For a use inside function minimise example. This was the optimized and operations research will often encounter problems )
