spread-spectrum

this program is an m-file of Model-based Predictive Control to track a sinusoidal target in various cases of mismatching and delay.

this program is made in matlab for executing

蒙特卡罗方法模拟137Cs源的662keVγ射线在NaI(Tl)闪烁体中的输运过程。开发环境:MATLAB(Monte Carlo simulation of 137Cs sources 662keVγ-ray in NaI (Tl) scintillator of the transport process. Development Environment: MATLAB)

部分实现了追踪测速迭代松弛算法，AHP层次分析法计算判断矩阵的最大特征值,小波包分析提取振动信号中的特征频率。( Partially achieved tracking speed iterative relaxation algorithm, Calculate the maximum eigenvalue judgment matrix of AHP, Wavelet packet analysis to extract vibration signal characteristic frequency.)

经典的SEP协议，代码完全正确，以及运行验证，对初学WSN路由协议的同学很有帮助。(Classic SEP protocol, the code is correct, and run the validation for beginner students WSN routing protocol is helpful.)

本文件内容是蒙特卡罗算法，主要是对一些被积函数难的多重积分进行估计，文档除了程序以外，还有详细的讲解，便于理解。(Contents of this document are the Monte Carlo algorithm, mainly for some of the integrand is difficult to estimate the multiple integration, documentation, in addition to the program, there are detailed explanations, easy to understand.)

数字水印，用MATLAB制作的，还有一些叙述情况(Digital Watermarking using MATLAB produced, and some described the situation)

u can calculate DCT clc inp = imread( Im1.jpg ) inp1 = imread( Im2.jpg ) A = double(inp(:,:,1)) B = double(inp1(:,:,1)) A1=double(blkproc(A,[8 8], dct2 )) B1=double(blkproc(B,[8 8], dct2 )) [r,c] = size(A1) r1 = [] for i=1:r for j=1:c if A1(i,j) > B1(i,j) r1(i,j)=A1(i,j) else r1(i,j)=B1(i,j) end end end r1= double(r1(:,:,1)) C=blkproc(r1,[8 8], idct2 ) round(C) C1=idct2(r1) figure imshow(uint8(C)) figure imshow(uint8(C1)) imwrite(uint8(C), dct8x8min.jpg )

matlab图像处理领域类的一种常用算法。对初学者有很大的帮助(matlab image processing class, a common algorithm. Very helpful for beginners)
