Frames adapted to a time-frequency cover By Jose Luis Romero , NuHag, Vienna Given a possibly irregular cover of the time-frequency plane, we construct dictionaries of atoms whose time-frequency profile (spectrogram) follows the given cover and show that these dictionaries provide frame expansions. The aim of this construction is to have a framework for time-frequency analysis, where the balance between time and frequency resolution is allowed to vary along the time-frequency plane..
