该文件时通信原理中的最基本的数字调制方式BPSK（二进制相移键控），希望对大家学习有帮助(When the file is the basic communication principle of digital modulation BPSK (binary phase shift keying), we hope to learn helpful)

资源分配的matlab文件，可以参考一下(resource allocation)

一篇英文文献，文中介绍的方法是先把图像分块，用熵值作为衡量每块图像的信息多少；计算每个图像块的熵值，熵值越大，信息含量就多。但是仅仅把熵值大的图像块拼在一起得到的融合图像有明显的不连续性，文中介绍了消除这种不连续性的方法(An English literature, the paper introduces the method is to first image block, using entropy as a measure of how much each piece of image information calculate the entropy of each image block, the greater the entropy, information content, the more. But only the entropy block large images side by side with the fused image obtained obvious discontinuity, the paper introduces the method to eliminate this discontinuity)

流行学习，改进Nystrom降维方法，很好用，欢迎下载(Improved Nystrom Kernel Low-rank Approximation)

说明：  MATLAB实现遗传算法求函数最大值，可以改变变量数目，函数形式(Seeking maximum MATLAB Genetic algorithms function, you can change the number of variables, functional form)

说明：  稀疏条件下欠定盲分离，得到混合矩阵，恢复原信号(Underdetermined blind separation under sparse conditions)
