Abstract
A system and method for post filtering signal peak reduction adapted for use in a multi-carrier communication system incorporating a source of a multi-carrier communication signal band limited in plural bands corresponding to the plural carriers. A first signal path receives as an input the band limited multi-carrier communication signal. A second parallel signal path includes a peak reduction calculation circuit for calculating a peak reduction correction signal and a plurality of filters providing a plurality of parallel filtering operations on the peak reduction correction signal corresponding to the plural bands to which the communication system is limited. The filtered peak reduction correction signals and delayed input signal are combined to provide peak adjusted output signals without violating the band limits of the communication signal or the modulation scheme of the communication signal.
