多用户检测 直接序列扩频 码解码部分(multiuser detesion)

分数付利叶变换的第二种算法 matlab程序(The m-file frft2.m computes the fast fractional Fourier transform following the algorithm)

说明：  matlab科学计算继续上传，一共10个章节，由浅入深，几乎包括了绝大部分的科学计算方法以及仿真。本人把部分算法做了优化，更为完善(matlab scientific computing continue to upload a total of 10 chapters, easy-to-digest, almost, including most of the scientific method of calculation and simulation. I have done a part of algorithm optimization, a more perfect)

说明：  这里面包括近百个matlab常用函数的例程，是学习matlab的好帮手。(This includes nearly one hundred matlab routines of commonly used functions, a good helper to learn matlab.)

This code use a Particle swarm optimization algorithm. and then optimize the learning rates of neural network. used is JENKIN s gasro and makey dataset.

说明：  Matlab下的大名鼎鼎的Leach分簇算法实现。对网络研究的有用处(Matlab under the well-known clustering algorithm Leach. Of network research useful)

matlab没有提供画椭圆的函数，该函数在获得椭圆中心 长轴轴 短轴后进行画椭圆，其中使用复变函数(did not draw an ellipse matlab function, the function in the long axis of the axis minor axis of the ellipse center painted oval, which use the complex function)

王兴刚和白翔合作发表的CVPR2011的文章， Feature Context for Object Detection and Image Classification，可以用于物体检测和图像的分类，用到了特征上下文，Feature Context(PROCEEDINGS and white Xiang cooperation the published CVPR2011 article Feature Context for Object Detection and Image Classification can be used for object detection and classification of the image, to use the features of the context, Feature Context)

三种esprit算法的doa估计matlab实现。参考张贤达《通信信号处理》的算法。包括两种普通esprit和TLS_esprit算法。经检查无误。(gfafsgfaqegfawegfgn asabqewgqaew)
