非线形混沌系统的庞加莱图的画法的代码以及其MATLAB m文件代码(Non-linear chaotic system Poincare map of the painting of the code and its MATLAB m-file code)

FDTD方法，以PML为边界条件，是二维的算法(FDTD method, the PML boundary condition is two-dimensional algorithm)

适合卫星通信本科学生借鉴。主要为卫星转发器仿真设计。可以实现上下变频，非线性放大器实现和卫星转发器实现。(Satellite transponder Simulation Design。Achieve Frequency conversion)

说明：  Regression sum of squares , the maximum deviation , minimum deviation , the average deviation

说明：  一个函数int fun(int *s,int t,int *k),用来求除数组的最大元素在数组中的下标并存放在k所指的储存单元中(A function int fun (int* s, int t, int* k), for requirements in addition to an array of the largest element in the array subscript coexist on the storage unit referred k)

数字喷泉码的仿真，使用C++语言所进行的仿真。(Simulation of digital fountain code, using C++ language for the simulation.)

说明：  用vb写的遗传算法程序。是一些通用代码，与具体问题对应的代码空出来，用的时候填进去。(used to write the genetic algorithm. Some common code, with the specific issues the corresponding code space, and the time spent filling into account.)

构造一个空的双向栈，判断双向栈是否存在，出栈，入栈，判栈空，将栈置空，判栈满，取栈顶(Construct an empty two-way stack to determine whether there is a two-way stack, out of stack, stack, sub-stack empty, set the stack is empty, sub-stack is full, take the stack)

本文基于MATLAB/SIMULINK动态仿真环境，以实例阐述了建立脉冲编码调制通信系统仿真模型的一般方法。根据该系统的基本原理将整个模型划分为抽样﹑量化﹑编码等几个子系统，并在传输线路上加入高斯白噪声以检验该系统的传输质量和抗干扰能力。(Title Design and Simulation for PCM communication system Abstract )
