training-validation The-Fold 10-fold 10-fold cross-validation
说明：这软件是用pisarenko方法、music方法、esprit方法来估计频率。-This software is used pisarenko way, music methods, esprit method to estimate the frequency.
说明：OFDM信号的时间偏差校正程序，用于估计OFDM信号的时间偏差-OFDM signals in time warp correction procedure used to estimate the OFDM signals in time warp
说明：利用FFT估计正弦信号的频率,要估计一个叠加了高斯白噪声的正弦信号 的频率 ，可以通过对x(n)做傅里叶变换，得到频谱图，找出幅度的最大值对应的频率值 ，进行多次变换，求出均方误差 。改变信噪比SNR，通过仿真可以得出随着信噪比增加，均方误差减小。
说明：ICA is used to classify text in extension to the latent semantic indexing framework. ICA show to align the context grouping structure well in a human ...
