matlab 语音混沌加密（logistic映射）带本机传输

说明：  AWGN和瑞丽信道的仿真程序，很不错，希望对大家有帮助(simulation for AWGN and RayLey channel，hope it s helpful!)

基于DCT和DWT的水印的嵌入与提取，以及鲁棒性的检测，攻击检测(Based on the DCT and DWT watermarking embedding and extraction, as well as the robustness of detection, attack detection)

说明：  该程序可以用于图像的显著性测试，首先能将图像根据超像素进行分割，再根据分割后的图像检测出图像中的显著区域。(We use the SLIC super pixel software to generate super pixel and some graph functions in the Graph Analysis Toolbox)

music静态DOA，经典算法，附有详细注释，适合学习。直接运行，是两个角度的DOA，可以改为三个信号，同时需要把子程序中的输出改成三个即可。(music static DOA, classical algorithm, with detailed notes, suitable for learning. Run directly, the DOA of two angles can be changed to three signals, at the same time need to change the output of the subroutine three can.)

针对镜头畸变失真模型，进行镜头畸变失真校正的小程序(Distortion model for lens distortion, lens distortion distortion correction for a small program)

Efficient signal processing techniques are necessary for assessing the exposure to broadband magnetic fields. The use of flat-top windows along with the DFT is a simple and fast method that reduces the characteristic leakage errors and picket fence effects when using the classical DFT for the exposure assessment.

二维图像FFT， DFT变换，并进行运行时间比较。

本程序是用来计算去趋势波动分析的MATLAB程序的(This procedure is used to calculate the detrended fluctuation analysis to the MATLAB program)
