Source code of AFIS (pattern recognition)

实现多用户MU，通过两次预编码来消除用户间干扰和流间干扰，同时这种处理极大简化了接收机复杂度。(MU-MIMO 。 the first precoding ：ZF-BD the second precoding ：ZF or MMSE)

说明：   1、 设有一个起始地址为FRIST + 1的数据块，存放在内部RAM， 数据块长度在FRIST单元且不为0，要求统计该数据块中值为0的个数， 并将它们分别存放在FRIST - 1单元单元，试编写出相应程序。(1, with a starting address FRIST+ 1 block of data stored in internal RAM, the data block length of 0 in the FRIST unit and not to require statistical data block 0 in the number of them were stored In FRIST- 1 unit cell, try to write the corresponding program.)

Denoising the Signals using Kalman Filter for Target Tracking in Wireless Sensor networks

同步MIMO-OFDM系统,分为SNR=10和SNR=20两种参数进行仿真。MATLAB程序。(Synchronous MIMO-OFDM system, into SNR = 10 SNR = 20 and two kinds of parameters for simulation. MATLAB.)

说明：  本程序实现了RGB图像转化为灰度图像，而后对图像进行了二值化，比较适合初学者，因为很多复杂的程序初学者比较难理解，我写的这个程序可以作为入门程序。(This program realized RGB images to gray image, and then to the binary image.It is suitable for beginners, because many complicated procedure is difficult for beginners, I write this program can be used as introductory programs.)

说明：  非常著名的爱尔朗公式的实现,主要对排队思想的进一步编程实现(Well-known Erlang formula to achieve, mainly on the line thinking further programming)

高斯平滑滤波，属于低通滤波，有效去除图像噪声。(Gaussian smoothing filter, a low pass filter effectively removes image noise.)

RBF神经网络的源程序，经过大量的测试，输入层、隐含层、输出层。(RBF neural network source code, after a lot of testing, the input layer, hidden layer and output layer.)

本算法能够按照两种策略生成并绘制随机图，但是对于生成的随机图的属性分析不够完善，从代码中能够看出作者并没有完成本算法关于“平均路径长度”、“聚类系数”和“平均度”三个属性的求解。(The algorithm is able to follow two strategies to generate and draw random graph, but for the properties generated random graph analysis is not perfect, it can be seen from the code of the algorithm is not complete on the "average path length", "clustering coefficient" and "the average degree of" solving the three properties)
