基于最低有效位lsb水印图象算法，带有攻击代码。(lsb watermarking algorithm,)

Phase vocoder is aprogram that allow you perform the shiftting pich without chort o long the time, using a factor value to do that

Modulation and Demodulation OFDM in matlab

先将47168bit的宿主音频等步长分段,分为1000段，然后混沌序列选择其中的102段，对每段进行3及小波分解，挑选出绝对值最大的系数，运用嵌入公式。(47168bit first step of the host audio sub-divided into section 1000, and then select one of the 102 chaotic sequence segment, on each piece of a 3 and wavelet decomposition, the largest absolute value coefficients selected using the embedded formula.)

降低OFDM系统峰均比的PTS算法源码，经过MATLAB仿真成功-Reduce the PAPR of OFDM system PTS algorithm source, after the success of MATLAB simulation (Reduce the PAPR OFDM system PTS algorithm source code, MATLAB simulations after the success-Reduce the PAPR of OFDM system PTS algorithm source, after the success of MATLAB simulation)

研一时做的音频检索的matlab代码，希望大家能用的上(Research a moment to do the audio retrieval matlab code, hope everyone can be on the)

matlab中关于dsp的全部程序 还有仿真模块 (matlab )

说明：  这是一个基于matlab的Hough变换源代码，很简洁但很实用(This is a Hough transform based on the matlab source code, very simple but very practical)

我自己编写的用遗传算法寻找KSW最佳二维阈值，搞噪效果很好。(I prepared using genetic algorithm to find the best 2D Threshold KSW, engage in noise with good results.)

雷达信号的模糊函数Matlab代码，包括线性调频信号，线性调频脉冲串信号，以及作为对照的单频信号。通过比较分析可以得到不同信号的模糊函数表现出的不同特征。(Radar chirp signal ambiguity function Matlab code, including linear FM signal, the chirp pulse train signal, as well as the control of the single-frequency signal.)
