查询词典 color spectrum

In order to eliminate the aliasing, at each step of decomposition or reconstruction, fast Fourier transform is performed the result obtained by convolving the input signal with filters, setting frequency spectrum of the redunctant frequency components to be zero, and inversely fast Fourier transforms the result after zeroing. The result after processing is the input signal of next step,and single sub-band reconstruction is implemented to extract the feature item of GPS data sequence.

为消除频率混淆现象，分解与重构时，每作一次信号与小波卷积后，将其结果作一次快速傅立叶变换，频谱中多余的频率成分的谱值置零，再对置零后的频谱进行傅立叶逆变换，然后继续进行小波包的分解与重构，从而实现单子带重构提取GPS数据序列特征项。
