This MATLAB Code plot the BER Vs Eb/No for M_ary FSK for differnt values of M. The user can choose the desired BER and the code will tell what is the required Eb/No to achieve this BER for differnt values of M. In addition, a plot of the shannon limit is available.

修改了现有的NSCT-tool中的混合C编程部分，所有步骤都通过matlab的矩阵运算完成，提升数倍的运行速度。(Modify existing NSCT-tool in a mixed C programming section, all the steps are completed by matlab matrix operations, increase several times speed.)

This code allows the development and application of methods of decoding and decryption of satellite system GLONASS.

matlab 版本的LDPC码的译码工具包，很实用(LDPC decoding tollkit of MATLAB Version)

阐述了S-Funtion的功能，如何使用，可以用C语言等程序编写自己的S-Funtion。扩展自己的Simulink性能。(Expound the fution of S-Funtion,and how to use it.you also can use C to make your own S-Funtion.So,you can expand the performance of Simulink.)

目标因子分析，用于找寻主因子数的个数，清晰明了的看出其步骤(Target factor analysis, to find the main number for the number of factors, see the steps clarity)

说明：  用Matlab实现亚当姆斯法，用来进行控制系统的仿真。(Using Matlab to achieve Adams method, used for control system emulation.)

图的着色问题的计算程序，根据输入的矩阵计算(Calculation program graph of coloring problem，base on the input matrix to calculat)

电力系统继电保护中方向阻抗型继电器仿真，在分布参数下构造“0接线”阻抗继电器模块，可对三相短路、两相短路和单相短路的出口故障、末端故障和外部故障进行仿真，得到各相继电器的相位，是研究阻抗保护的有效工具。(Power system protection in the direction of the impedance relay simulation, the distribution parameters structure " 0 Connection" impedance relay module, the simulation of three-phase short circuit, two-phase short-circuit and export single-phase short circuit fault, the end of the fault and external fault, the phase of each phase relay is an effective tool to study the impedance protection.)

说明：  医学成像技术滤波反投影 内含R-L， R-S sweit滤波 重建后图像清晰，效果相当好(medical imaging technology filter-projection includes R-L, R-S sweit filtering reconstruction after the pictures are clear, the results are pretty good)
