PROPERTIES OF RANDOM SIGNALS IN WAVELET DOMAIN

PROPERTIES OF RANDOM SIGNALS IN WAVELET DOMAIN

In many applications (e,g., identification of non-destructive testing signal and biomedical signal and multiscale analysis of image), it is of interest to analyze and identify phenomena occurring at the different scales. The recently introduced wave let transforms provide a time-scale decomposition of signals that offers the possibility of such signals. However, there is no corresponding statistical properties to development of multiscale statistical signal processing. In this paper, we derive such properties of random signals in wavelet domain.
