Density conditions including necessary ones and sufficient ones for irregular wavelet systems to be frames are studied in this paper. We give a definition of affine Beurling density of time-scale parameters and show that for irregular wavelet systems to be Bessel sequences, the time-scale parameters

In this paper we show that there exist wavelet frames that have nice dual wavelet frames, but for which the canonical dual frame does not consist of wavelets, i.e., cannot be generated by the translates and dilates of a single function. ο 2002 Elsevier Science (USA)
