General idea of the super-resolution method based on the signal-spectrum extrapolation beyond transmission-channel band has been presented. Main limitations of former realizations of the method have been discussed. A new realization procedure of the method, removing those limitations, has been proposed. It consists in signal fragmentation before transmission through a low-pass channel. Results of a few numerical experiments done by means of original computing tools has been presented and discussed.
