基于DCT的图像信息隐藏于提取，隐藏位置为随机数列确定(DCT-based image information hiding in the extraction, hidden location to determine a random series)

thanx u gav me a nice option to upload and take models

在Juan Cardelino发布的FMM(fast marching methos)2维程序基础上改写的3维程序。并改写成适合复杂速度模型，可用于地震旅行时计算。大模型3d算法在matlab下计算速度较慢，根据源码中的注释很容易改写成c程序。(3D FMM program revised from Juan Cardelino s 2D version. The program can calculate the seismic traveltimes in 3D complex model)

遗传算法解决背包问题。内含genetic工具包。(Genetic algorithm to solve knapsack problem. Contains genetic toolkit.)

关于OFDM的matlab仿真，调制、解调以及误码分析(On the OFDM simulation, modulation and demodulation error analysis)

With this document, is intended to show some manipulation of signal processing techniques regarding continue and discrete signals, odd and even components, and periodic discreet signal, showing the mathematical part and the source code in Matlab on which it’s possible to try it out.

费聂耳衍射成像的模拟，采用透镜成像原理，有效地利用fft(simulation of the diffraction，based on the optical lens and the theory of fft)

说明：  喷泉码译码过程， MATLAB 编写， BEC信道(Fountain code decoding process, MATLAB preparation, BEC channel)

传感器网络的关系，半径和程序中的节点数的连通概率和通信，利用MATLAB软件对部署图的计算机模拟(The relationship of sensor networks, the connectivity probability and communication radius and the number of nodes in the program, use the Matlab software on the computer simulation of deployment and mapping)

对《合成孔径雷达——算法与仿真实现》光盘的文件进行提取转换为》dat文件(On " Synthetic Aperture Radar- Algorithm and Simulation" CD-ROM file extraction converted to " dat file)
