现代通信系统，第五章，课后作业题目的MATLAB源代码程序(Modern communication systems, chapter, after-school job)

说明：  假设时变系统的特性用一个系数为时间函数的n阶微分方程的形式来描述，仿真该系统(Assuming time-varying characteristics of the system as a function of time with a coefficient of order n in the form of differential equations to describe the simulation of the system)

SPIDER是测量超短脉冲的一种有效方法，该程序给出了基于Matlab的SPIDER代码，它可以直接运行。(SPIDER is one of the effective approaches to measure the pluse durantion.This program is the code of SPIDER based on Matlab.It can easily be ulited.)

EMD算法的完整Matlab程序，包含了多种形式的EMD算法。(EMD algorithm integrity Matlab procedures, including various forms of EMD algorithm.)

This InstructionVisitor executes the instructions that it visits on a given local variable frame and stack.

改进欧氏距离测度算法，可以比较特征向量的距离相似度(Improved algorithm Euclidean distance measure, you can compare the similarity distance of feature vectors)

说明：  这个是卷积编码程序的m文件， 已经调通！并加上了注释。(This is a convolutional coding process m-files have been transferred Pass! And add a comment.)

利用matlab实现光纤的模式分布图的模拟。(Using matlab to achieve mode fiber distribution simulations.)

music算法的实现。区分多个频率相邻信号效果明显(music algorithm. Separate multiple frequency adjacent signal effect is obvious)
