傅里叶变换后频谱图
B:陷波函数作用后的频谱图
C:经逆变换的滤波后图像,效果不是很理想
Ifft2:为验证自己的快速傅里叶变换程序的正确性,用matlab自带逆变换程序将频谱逆变换后图形,与原图相符,说明快速傅里叶变换程序正确。(This is a FFT )

Synchronize
说明: 由于使用了大量数目的子载波,这就使得多载波系统对多种同步误差都很敏
感。同步误差可分为两大类:载波相位
(due to the use of the large number of subcarriers, which makes multi-carrier systems for a variety of synchronization errors are very sensitive. Synchronization error can be divided into two categories : carrier phase)

DecisionTreeBasedOnHiberarchyDecomposition
传统的决策树能较好地解决分类问题,但当类的个数增多时,所产生的单一决策树就会变得复杂,同时概括能力降低。 该文采用基于层次分解的方法通过产生多层决策树来处理多类问题。 与传统的单一决策树比较, 基于层次分解的决策树在处理多类问题时有许多的优势。(induction learning,decision tree,id3 ,hiberarchy decomposition)

fldc_d_4_as
基于分数低阶协方差仿真的时延估计问题,其基本思想是利用两个接收信号的相关函数来估计时间延迟。(Based on the scores of low-level simulation of time delay covariance estimation problem, the basic idea is to use of the two received signal correlation function to estimate the time delay.)
