Nonuniform M-band wavepackets for transient signal detection

In this paper, we present a scheme to detect significantly overlapping transients buried in white Gaussian noise. A nonuniform M-band wavepacket decomposition algorithm using M-band, translation-invariant wavelet transform (NMTI) is developed, and its application to transient signal detection is discussed. The robustness of the NMTI-based detector is illustrated.
