Mathematica教程，包含12个章节，叙述详细，可以满足基本需求(Mathematica tutorial contains 12 chapters, describes in detail, to meet basic needs)

本文件夹的程序是基于WaveLab802平台作的。 包括以下方法： VisuShrink方法、SUREShrink方法、BayesShrink方法、AdaptBayesShrink方法、 LAWMLShrink方法。(The program in this folder the is based WaveLab802 platform. Including the following methods: The method VisuShrink, SUREShrink methods, BayesShrink methods, AdaptBayesShrink method LAWMLShrink method.)

PHAT-based cross correlation

设计一个程序，用后向Euler 法/梯形法求解电路系统的MNA 方程（该方程由stamp 程 序得到），其中线性方程的求解采用GCR 迭代法。(Design a program that uses the backward Euler method/trapezoid method for solving circuit system MNA equation (the equation obtained by the stamp program), in which the linear equations using GCR iteration.)

16QAM调制OFDM系统仿真示例，实现OFDM系统各部分的基本功能(16QAM modulation OFDM system simulation example, the realization of OFDM system basic functions of each part)

The model of Eye Diagram and its histogram

16QAM编译码程序，在信号调制过程中是不可缺少的成分(16QAM encoding and decoding process, in the course of signal modulation is an indispensable ingredient)

(1) 新建一个工程demo2，设计一个类Student，其成员变量包括学号(no)、姓名(name)、性别(sex)、专业(major)、联系方式(phone)和地址(addr)。 (2) 为类Student定义成员函数writeTo，实现从给定文本文件中读取学生数据，接口如下： void writeTo (char filename[ ]) (3) 为类Student定义成员函数readFrom，实现将学生数据保存到给定文本文件，接口如下： void readFrom (char filename[ ]) ((1) Create a new project demo2, design a class Student, whose member variables, including school (no), name (name), gender (sex), specialty (major), contact details (phone) and address (addr). (2) define the Student class member function writeTo, students achieve reading data a given text file, the interface is as follows: void writeTo (char filename []) (3) define the Student class member function readFrom, students will achieve data save to text file given, the interface is as follows: void readFrom (char filename []) )

说明：  根据传统材料力学势能法来进行数值分析计算健康齿轮时变啮合刚度(Calculating the time varying mesh stiffness of perfect gear based on potential energy method)

Time-frequency representations with fixed windows or kernels figure prominently in many applications, but perform well only for limited classes of signals.
