this simulation is a way for watermarking and steganography with HUGO

信号的希尔伯特-黄变换，IMF分解，对IMF进行Hilbert处理，绘制二维/三维时-频图，时间-能量图(瞬时能量谱) ，频率-能量图（希尔伯特谱）(Hilbert signals- Huang Transform, IMF decomposition of the IMF Hilbert processing, rendering 2D/3D time- frequency diagram, time- energy (instantaneous energy spectrum), the frequency- energy (Hilbert spectrum))

说明：  2012版本以后就没有这个函数了，希望对大家有用，有问题私信我(modmap in matlab thanks)

Various routines that simulate or compute aspects of digital communication systems

说明：  这是一个建立在OMP算法基础上，笔者自己提出来的一个稀疏分解的DOA估计算法，利用阵列流形矢量间的不相关进行匹配追踪选择，选出与信源位置流形最接近的，以便求得DOA(This is a building based on the algorithm of OMP, the author himself a sparse decomposition algorithm for DOA estimation, using the array manifold a vector between the related matching track selection, and choose the source position manifold closest, in order to obtain DOA)

Complex wavelet structure similary

说明：  1. 编程实现图像傅立叶高通、低通滤波。 2. 尝试傅立叶压缩。 (1. Programming image Fourier high-pass, low pass filtering. 2. Try Fourier compression.)

分数阶傅立叶变换的示例程序，个人成果，仅供参考(Fractional Fourier transform of the sample program, individual results, for reference only)
