The invention discloses a method for eliminating signal wave, which comprises the following steps: after the IFFT transform on the physical layer signal to sidelobe peak of RC1 operation; the signal sidelobe peak of RC1 operation of the digital up converter DUC frequency filter; to the filtered intermediate frequency signal DUC sidelobe peak RC2 operation; among them, the sidelobe peak RC1 operation including mainlobe peak operation, the sidelobe peak RC2 peak clipping operation including full flap operation. The technical scheme provided by the invention can eliminate the peak power of any sub carrier configuration. In addition, the technical proposal provided by the invention consumes less hardware equipment resources and has less processing delay.
