Zusammenfassung:Goal of the application is providing an alternative to the N-continuous algorithm in frequency domain for sidelobes reduction (OOB) suitable for SC-FDMA. A part of the time domain symbols is used as correction signal to ensure continuity of the signal and its derivatives at symbol boundaries, ie between previous symbol and guard interval (can be Zero Padding or Cyclic Pre-fix) of current symbol. Said time domain symbols are then FFT precoded, windowed, followed by IFFT and Guard Interval insertion. Also applied to FBMC.
