Paper Abstract

This paper develops a signal detection scheme based on the wavelet packet theory, which has been introduced recently as an effective signal analysis tool by M.V. Wikerhauser. As we all know, for the detection of transient signals with unknown arrival times, there is no uniformly tool because the detector performance usually depends on the signal representation. If all the signal components are similar, our method, called wavelet packet detection algorithm (WPDA), provides the possibility of detecting different arrival times correctly, even in the case that their waveforms overlap too much. As a comparison, the Improved Gabor Representation Method is utilized. The experiments show that WPDA can achieve more satisfactory performance.
