分段平均法功率谱分析，不同数据重叠长度对结果的影响 (Sub-average power spectrum analysis, the results of different data length on the impact of overlapping)

It is great model of one part of engine diesel model. This particular file contains model of EGR valve. .

adaptive filter harmonic estimation

chirp信号生成，以及匹配滤波实现，卷积实现(chirp signal generation and matched filtering to achieve)

实现了用LSB嵌入水印，还有两种水印分析方法：X2和信息量分析法(Achieved using LSB embedding the watermark, there are two kinds of watermarks analysis methods: X2 and the amount of information analysis)

本函数是一个通过设置阈值，检测基本通信水印的函数(This function is a through setting threshold value, the function of the basic communication watermark detection)

四轴飞行器Matlab仿真分析，涉及四轴飞行器主要部件如Mottor，camera，电池等，分析包含稳定性、动力等 已通过测试。 (VRML simulation on the real life in a common environment (multimedia classroom), very often realistic image, the code is very long, but it is easier to understand. Has been tested.)

实现信号的SVD 分解,对信号中的奇异性进行监测，对突变信号点也可以很好监测(to complete the SVD for signals，Singularity of signal monitoring, signal monitoring point can be very good for mutations)
