Since the wavelet power spectra are distorted at databoundaries (the cone of influence, COI), using traditionalmethods, one cannot judge whether there is a significant regionin COI or not. In this paper, with the help of a first-order autoregressive (AR1) extension and using our simple andrigorous method, we can obtain realistic significant regions andintrinsic feature in the COI of wavelet power spectra. We verifyour method using the 300 year record of ice extent in the Baltic Sea.
