matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如修改不严重，可提取隐藏信息，如果修改过多，则只能确定是否有修改，而不知道隐藏的信息是什么(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, such as modification is not serious, can extract hidden information, if too many modifications, you can only determine whether changes were needed, they do not know what information is hidden)

系统辨识与MATLAB仿真程序与剖析,CH3,CH4,CH6程序注释与剖析(system identification and MATLAB simulation and analysis, CH3, CH4, fragments and analysis procedures Notes)

运用一种基于相位信息的2FSK与MSK的调制识别方法,来实现MSK与普通的2FSK的识别。通过计算机仿真表明,在SNRE10dB的条件下,该方法识别率达到了100 。 (Based 2FSK use and MSK modulation recognition phase information to achieve a common 2FSK MSK and identification. Through computer simulations show that, under SNRE10dB conditions, the recognition rate reached 100 .)

该程序是完整的TLD跟踪算法过程，采用matlab和C语言混合编程技术，并有测试图片(The program is a complete TLD process tracking algorithm, using matlab and C language programming mix, and a test image)

对均匀线阵环境下的来波方向进行估计，分别用了MUSIC算法以及ESPRIT算法进行仿真。(DOA for ULA environment estimate, respectively, with the MUSIC algorithm and ESPRIT algorithm simulation.)

Multiwavelet wavelet theory has become a hot one, it is more than wavelet function and a number of scaling function to indicate signal. [1] using fractal interpolation function is the first of a multi-wavelet, as GHM Multiwavelets.
