一些关于信号处理谱分析的MATLAB代码，对学习频谱分析比较有用(some code for study spectrum_analysis in signal processing are very useful.)

factor of 32, with acceptable quality.What are the principles behind compression?A common characteristic of most images is that the neighboring pixels are correlated and therefore contain redundant information. The foremost task then is to find less correlated representation of the image. Two fundamental components of compression are redundancy and irrelevancy reduction. Redundancy

digital watermarking is a process by which a user-specified signal is hidden or embedded into another signal , for example digital content such as electronic documents, images, sounds and video [2]. The use of digital video applications such as video-conferencing, digital television, digital cinema, distance learning, videophone, and video-on-demand has grown very rapidly over the last few years. Today it is much easier for the digital data owners to transfer multimedia data over the internet, and hence the data could be perfectly duplicated and rapidly redistributed on a large scale. Thus, the importance of copyright protection for multimedia data has become more critical. Digital watermarking is an effective way to protect the copyright of multimedia data even after its transmission there is urgent demand for techniques to protect the original digital data and to prevent unauthorized duplication or tampering.

文章在传统的分散压缩感知理论的基础上提出了一种新的联合压缩感知新算法，利用所要恢复的信号之间的相关性进一步减少所需要的采样点。(Scattered articles in the traditional theory of compressed sensing based on the proposed joint compression, a new perception of the new algorithm, using the signals to restore the correlation between the need to further reduce the sampling points.)
