基于M带小波的GPS信号特征信息探测

The study of extracting feature information from GPS signal using M-band wavelet

为了有效探测、提取GPS时间序列中的特征项,在分析二带小波的基础上,研究了M带小波,利用M带小波的单子带重构改进算法对GPS序列进行多通道分解,提取了信号中的弱特征项,取得了良好的效果.

In order to detect and extract the GPS time series,on the basis of the analysis by the wavelet-spectrum and the study of the M-band wavelet,the better effect can be obtained,using the improved M-band wavelet single-sub-band-reconstraction algorithm to extract the low amplitude composition in signal.
