说明：  该文件包含用MATLAB实现的OFDM 的源程序(Channel estimation for a MIMO-OFDM system)

小波分析理论及MATLAB7实现的例程,第18章 小波变换在故障诊断中的应用(Wavelet analysis theory and realize MATLAB7 the routines, Chapter 18 Application of Wavelet Transform to Fault Diagnosis)

本程序实现多模态故障检测与故障诊断，用的方法是LPP_GMM_FJ，对象为CSTH,GMM是用的FJ算法，效果很好(This procedure realize multimodal, fault detection and fault diagnosis method is LPP_GMM_FJ, object for CSTH, GMM FJ algorithm is used, the effect is very good)

这是一本关于雷达系统仿真的matlab英文书，非常系统的介绍了雷达系统的仿真。(This is the one on the radar system simulation matlab English books, very systematic introduction to the radar system simulation.)

MATLAB GUI 两个信号波形叠加合成，其中一个含有参数，界面上通过改变参数得出相应的合成波形(MATLAB GUI two superimposed signal waveform synthesis, one of which contains a parameter, the interface by changing the parameters of the corresponding synthetic waveforms obtained)

说明：  图4.7给出了V=4，相位集合的相位数分别为P=1、2、4、8时的随机分割的PTS-OFDM系统的CCDF的性能图。仿真参数：分割方法为随机分割，子载波数N=128，子载波数据采用QPSK调制，仿真的OFDM符号数为1000个。(Figure 4.7 shows the V = 4, the phase of the collection phase, respectively P = 1,2,4,8 were separated when the PTS-OFDM system performance CCDF graph. Simulation parameters: Segmentation of random division, the number of subcarriers N = 128, sub-carrier data using QPSK modulation, simulation of the OFDM symbol number 1000.)
