In last years, the time-frequency distributions issued by wavelet packet decomposition or matching pursuit have been more and more used, due to the possibility to extract the information about local signal singularity. The main problem is the choice of decomposition parameters, such as decomposition level or wavelet family.
In this paper we consider the problem of transitory signal characterization, extracted from the underwater environment. The main difficulty which appears in this field is due to the transient behavior of the received signals and to the noise level of the underwater environment. In fact, in the received signal structure a transient part occupies only a small zone and its capture can be done by an adaptive...
