Abstract
Estimates of frame bounds for wavelet frames generated by discrete sets in phase space satisfying only a certain density condition are deduced. Numerical examples show that these estimates, which are the sharpest results of this kind known to the authors, are rather poor compared to Daubechies´ estimates (see ibid., vol.36, no.5, p.961-1005, 1990) for the usual discrete wavelet transforms.<>
