看了一段时间的3GPP的信道建模，所以自己动手写了一个（参考了该协会的标准代码，不过改良了一些，执行效率更高）(the 3GPP SCM model building. Comparing to the original code, this task is more efficient and clearer.)

spider，很好用的模式识别工具箱，里面有各种分类工具，从有监督学习到无监督学习，从模型选择到参数选择。而且也将各个方法封装成类，使用方便。(spider, good use of pattern recognition toolbox, there are various classification tools, from supervised learning to unsupervised learning, choose Preferences from the model. But also the various methods into a class package, easy to use.)

对二维图像进行离散傅里叶变换，分别给出了直流分量移动到频谱中心前后的频谱图样。(Two-dimensional images of the discrete Fourier transform, respectively, given the spectrum to move to the DC component of the spectrum before and after the design center.)
