MATLAB在振动信号处理中的应用1

c++ learning 讲授对于初学者有很大帮助，对于熟悉着可以参考下-c++ learning to teach have much help for beginners, for those familiar with a can refer to the next

实习课题----VC-attachment issues- VC

说明：  OFDM的MATLAB系统仿真，使用QPSK调制、梳状导频LS信道估计，并且还进行了LS和MMSE信道估计方法的性能比较(MATLAB simulation of the OFDM system, QPSK modulation, combed pilot LS channel estimation, and performance comparison of LS and MMSE channel estimation )

说明：  通过matlab建立模型，用于函数的梯度优化算法，显示迭代坐标(The model is established by MATLAB, which is used for gradient optimization algorithm of function and shows iterative coordinates)

CHM decompiler is a program that converts the internal files of CHM files back into the HHP, HHC, and HHK, etc. used to compile the documentation. CHM decompiler是一个把CHM 文件的内部文件转换成 HHP, HHC,和HHK等的程序。它用于编译文件。-CHM decompiler is a program that converts the internal files of CHM files back into the HHP, HHC, and HHK, etc. used to compile the documentation. CHM decompiler is transforms the CHM document house document HHP, HHC, with HHK and so on procedure. It uses in to translate the document.

说明：  spss相关数据文件， 以供平时练习使用。 400份关于学生与父母沟通情况的调查问卷。((SPSS related data files, For the usual practice.))

用于运动会的统计.分数,那女子参赛情况的记录统计.(Statistics for the Games. Scores, and that the situation of the women)

也是用C语言编写的通讯录小程序，以前学C语言设计时做的，希望有所帮助。-，，

出来的图形是混沌图形，但是x，y，z分解后为有规律曲线，与信号类似，说明信号的叠加或许是一种混沌系统(The figure is chaotic, but x, y, Z are decomposed into regular curves, similar to signals, indicating that the superposition of the signals may be a chaotic system.)

说明：  matlab中调用ansys进行计算，有例子和调用说明word(In matlab, we call ANSYS for calculation. There are examples and call description word.)
