Image Watermarking using DWT algorithm

利用振荡器的相位同步特性进行简单的图像恢复(use the synchronization of oscillators array to recover a pattern)

这个程序用matlab演示扩频及其频谱。(Matlab demo using this procedure and its Spread the spectrum.)

使用高阶累积量对MPSK信号进行调制识别，效果很好，可以达到很高的识别率，我曾论证了好久，确定它的结果没有问题，确实识别率很高(Modulation recognition of MPSK signals using higher order cumulants good effect, and can achieve a high recognition rate, I have argued for a long time, and its results, is indeed a high recognition rate)

稳定时期为单位汽车完善的需求为单位DDFCWECDWCSCSC测定出稳定舞动长裙生产线(In cognitive radio networks, power control is considered as an important issue to improve the performance of dynamic spectrum sharing. In this paper, in order to maximize the efficiency of the system, the secondary users and primary user behaviors will be considered. )

用Mathematica写的一个基于分水岭的图像分割算法，过程很详细。(Using Mathematica write a watershed-based image segmentation algorithm, the process in great detail.)

此程序是matlab中给出连续系统的s函数，给出了如何在simulink中建立一个变量，注释详尽，使用简单，其中的注释详细，自己可以对变量做相应的变换(This procedure is given in matlab continuous system s function is given how to create a simulink variables, comments, detailed, easy to use, which notes in detail that they can make the corresponding change of variables)

求极小值，最优化方法的一个matlab范例(Seek the minimum value, a Matlab example of optimization methods)

Basic fullvector waveguide : Illustrates the basic usage of the full-vector modesolver to find Hx and Hy for a simple ridge waveguide.

海洋科学导论的书籍，对于搞SAR和海洋的人有帮助(Introduction to marine science books, for people who engage in SAR and ocean help)
