MATLAB中移动通信的仿真的用法，比较基本的，比如信号的产生 加噪等等(MATLAB, the simulation of mobile communications usage, more basic, such as signal plus noise, and so produce)

单边指数信号M文件，可生成单边指数信号频谱，希望对大家有帮助(Pors)

matlab 下OFDM信号的产生、发送和接收以及误码率分析等(matlab generated under the OFDM signal, send and receive, and BER analysis)

电力系统专业本科生可以看下，用于计算三机九节点系统的潮流(calculation of the power flow)

S－函数是System function 系统函数的简称，是指采用非图形化（即计算机语言，而非Simulink 系统模块）的方式描述的功能模块。在MATLAB 中，用户除了可以使用MATLAB 代码编写S－函数以外，还 可以使用C、C＋＋、FORTRAN 或Ada 语言编写S－函数，只不过用这些语言编写程序时需要用编译器生成 动态连接库（DLL）文件，然后在Simulink 中直接调用(S-function System Function system function, refers to the use of non-graphical (ie computer language, rather than the Simulink system module) way described functional modules. In MATLAB, the user can use MATLAB code to write the S-function outside can use C, C++, FORTRAN or Ada language preparation of the S-function, only in these languages ​ ​ to write programs need to use the compiler to generate dynamic link library (DLL ) file, and then called directly in Simulink)

将系数矩阵A转变成等价两个矩阵L和U的乘积 ，其中L和U分别是下三角和上三角矩阵。当A的所有顺序主子式都不为0时，矩阵A可以唯一的分解为A=LU。其中L是单位下三角矩阵，U是上三角矩阵。 (The coefficient matrix A into two matrices L and U is equivalent to the product, where L and U are lower triangular and upper triangular matrix. When A master style is not all the sequence is 0, the matrix A can only be decomposed into A = LU. Where L is unit lower triangular matrix, U is upper triangular matrix.)

关于高阶64APSK的优化设计程序，包括个圆半径的设置，相位角的设计，已达到最好的误码率特性(Higher order 64APSK optimal design program, including the setting of a radius of a circle, the phase angles have been designed to achieve the best error rate characteristic)
