SVD-watermarking

说明：  南京航空航天大学的关于波束形成算法及其新进展的PPT,适合初学者学习了解(This is the PPT about alograthms of beams-forming from NUAA. This is a very good start for students who are not familiar with this area. )

双目资料，很好的学习资料，帮助很大，谢谢大家(Binocular information, good learning materials, helpful, thank you)

使用viterbi方法译码的源代码，可以绘制最佳路径选择过程的仿真图(Viterbi decoding method using the source code, you can draw the best path selection process simulation diagram)

计算标准大气特性的matlab代码，基于美国1976年的测试数据(source code in matlab for computing atmospheric characterics, based on the Data obtained in 1976 )

能求取放在M文件旁边文件的HU不变矩！经反复检验出错(Can strike the HU on the M-file next to the file the same moment!)

matlab 的小波去噪界面设计，在图像进行小波分解，给高频部分滤除，在进行中值滤波哦，最后合成(Wavelet denoising matlab interface design, image wavelet decomposition, to filter out the high frequency part, during the median filtering Oh, the final synthesis)

BER性能分析。参数开放，宜用。多给意见。(BER performance analysis. Parameters of open and suitable. Give advice.)

本例用五点差分法求解一个二阶偏微分方程，其间用Gauss-Seidel迭代求解(This example uses a five-point difference method for solving second order partial differential equations, during use Gauss-Seidel iterative)

Step 1: Set i=1 FA=f(a) Step 2: while i≤ No do step 3-6. Step 3 set p=(a+b)/2 FP=f(p) Step 4 if FP<TOL or (b-a)/2<TOL then OUTPUT(p) STOP. Step 5 set i=i+1 Step 6 if FA.FP > 0 then set a=p FA=FP else set b=p. Step 7 OUTPUT (‘Method failed after No iteration,No=’, No) STOP.
