3.6
主要用途是对抗多径衰落。由于多径衰落的存在,使得同一个帧由于路径不同,到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰,影响 性能。另外,由于有了循环前缀,使得IFFT FFT操作把原来的线性卷积变成循环卷积,大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

Demo_lraNMF
我现在主要研究的是非负矩阵在特征提取方面的工作,上传几个我阅读的外国文献的,书籍源代码,在代码中有相应的文献或综述。我就上传一个low rank NMF的。压缩包里有9个文件。(I now mainly studied non-negative matrix feature extraction work, and upload a few I read foreign literature, books source code, there is a corresponding review of the literature or in the code. I' ll upload a low rank NMF' s. Compression bag has nine files.)
