Abstract
A system and method for post filtering signal peak reduction adapted for use in a communication system incorporating a source of a communication signal band limited in a manner corresponding to a spectral band to which the communication system is limited. A first signal path receives as an input the band limited communication signal. A second parallel signal path includes a peak reduction calculation unit for calculating a peak reduction correction signal and a filter providing a filtering operation on the peak reduction correction signal corresponding to the spectral band to which the communication system is limited. The filtered peak reduction correction signal 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.
