Frames adapted to a time-frequency cover\n\nBy Jose Luis Romero \, NuHag\, Vienna\n\nGiven a possibly irregular cover of the time-frequency\nplane\, we construct dictionaries of atoms whose time-frequency profile\n(spectrogram) follows the given cover and show that these dictionaries\nprovide frame expansions. The aim of this construction is to have a\nframework for time-frequency analysis\, where the balance between time\nand frequency resolution is allowed to vary along the time-frequency\nplane..
