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

Shaped_Histograms
Thresholding is used to segment an image by setting all pixels whose intensity values are above a threshold to a foreground value and all the remaining pixels to a background value.
Whereas the conventional thresholding operator uses a global threshold for all pixels, adaptive thresholding changes the threshold dynamically over the image. This more sophisticated version of thresholding can accommodate changing lighting conditions in the image, e.g. those occurring as a result of a strong illumination gradient or shadows.ff
