LDPC编译码算法研究，BP译码算法，高斯白噪声信道，码率0.5(LDPC encoding and decoding algorithm, BP decoding algorithm, Gaussian white noise channel, bit rate 0.5)

应用matlab 对图像进行灰度加强处理，相当不错！！！！！(image process)

永磁同步电机调速系统，采用模糊PI进行速度控制，常规PI进行电流控制(Permanent magnet synchronous motor speed control system, using fuzzy PI speed control, the conventional PI current control)

说明：  matlab仿真实现模糊逻辑，对解决多属性问题有很大帮助(Fuzzy Logic using matlab)

我们做很多实验时得到的一些数字信号必须经过处理才能最终得到应用。此文件是matlab数字信号处理说明书，希望对读者有帮助(We do a lot of experiments to get some of the digital signal must be processed in order to ultimately be applied. This file is matlab digital signal processing instructions, hoping to help the reader)

这一段源代码为瑞利衰落信道的实现，代码比较简单，适合初学者学习(This section of the source code for the realization of Rayleigh fading channel, the code is relatively simple, suitable for beginners to learn)

该程序用于计算n根平行导线间的串扰,程序结构及说明见程序内。源可以是单频的或脉冲的（这里给出的是频域的）。频率、波形、线长、电源及负载阻抗均可在用MATLAB编写的语句中方便地修改。但必须输入导线系统每单位长度的电感、电容矩阵。(The procedure used to calculate n root of crosstalk between parallel wires, program structure and description of process. Source can be single frequency or pulse (here is given by the frequency domain). Frequency, waveform, the line is long, power and load impedance can be found in the use of MATLAB statements prepared easily modified. However, the system must enter a wire per unit length inductance, capacitance matrix.)
