一个基于边信息嵌入的数字水印程序,经过本人的实验,已实现,供各位享用(A side information embedded based on digital watermarking process, after my experiments have been realized, for your enjoyment)

nonlocal mean for 2-D 3-D IMAGE PROCESSING

设计的带通滤波器方法 改变参数就行了 里面有几种方法(designed band pass filter change of parameters on a trip inside there are several ways)

y3k=fft(u,(m+n-2)/4) i=1:(m+n-2)/4 subplot(5,2,9) stem(i,u) title( 滤波后上采样 ) k=1:(m+n-2)/4 subplot(5,2,10) stem(k,y3k) title( 上采样频谱 ) xlabel( k ) ylabel( y3k ) (y3k = fft (u, (m+ n-2)/4) i = 1: (m+ n-2)/4 subplot (5,2,9) stem (i, u) title (after filtering the sample) k = 1: (m+ n-2)/4 subplot (5,2,10) stem (k, y3k) title (on the sample spectrum) xlabel (k) ylabel (y3k))

在DAB系统中的频率同步，载频同步，参考一下Carrier frequency offset estimation of DAB receiver based on phase reference symbol(In the DAB system frequency synchronization, carrier frequency synchronization, refer to Carrier frequency offset estimation of DAB receiver based on phase reference symbol)

用ＭＡＴＬＡＢ实现正交频分复用（ＯＦＤＭ）信道的模拟(Using MATLAB to achieve orthogonal frequency division multiplexing (OFDM) channel simulation)

MATLAB 数学手册完整版 很实用,是word版本(MATLAB Mathmatical Guide Complete version )

说明：  最小生成树的kruskal算法 自己写的 要是再说有重复 我可就怒了(the Kruskal minimum spanning tree algorithm wrote it myself if I say that there is no duplication of anger on)
