SVD-DCT_Image_watermarking

HHT源代码 做时频分析的同志们可以看一下 相当经典的例子(HHT time-frequency analysis of the source code to do the comrades can look very classic example of)

产生随机信号观测样本，不同信噪比和归一化频率。利用基于FFT的自相关函数快速计算方法估计其自相关函数。(Generate random signal observation samples, different signal to noise ratio and normalized frequency.Based on FFT calculation method of the autocorrelation function to quickly estimate the autocorrelation function.)

说明：  压缩感知重构算法之正交匹配追踪（omp）及其matlab实现，小波,进行压缩感知，只含代码。(Orthogonal matching tracking (omp) of compressed sensing reconstruction algorithm and its matlab implementation, wavelet, compressed sensing, including only code.)

协作通信中的af-df转发源码，matlab版本 (Cooperative communications forward in af-df source, matlab version)

说明：  机载雷达多点目标成像，自己根据某型无人机载SAR成像运动补偿研究参数编写的，希望大家指正(Airborne radar multi-target imaging, own a certain type of UAV based on motion compensation of SAR imaging parameters of prepared, I hope you correct me)

本段代码用于检测在雷达中的SMSP干扰，为后续的干扰抑制提供先验信息(This Code is used to detect SMSP jamming)

matlab课程编程【谷速软件】2DPCA算法设计 可以作为参考使用学习(matlab programming courses [Valley] 2DPCA algorithm speed software designed to use as a reference to learn)
