Detection of Signals in Noise Bases on Wavelet Transform
1998
Absrrucr Wavelet analysis is a multiresolution analysis, whose elements has good localization properties in both the spatial and Fourier domains, For different frequencies it has a changeable time-frequency window, so the detector bases on wavelet transform is robust. In this paper the detection of signals in noise is discussed and a concept of multiresolution likelihood ratio is put out .
