Abstract
This disclosure relates to a peak reduction circuit and method for reducing peaks by identifying peak sample values exceeding a pre-set threshold value in an aggregated baseband carrier signal and determining a maximum peak sample by detecting its maximum peak absolute value and phase. A search is performed a pre-determined search length beyond an identified peak. A stored, predetermined filter impulse response based on the carrier passband configuration is retrieved and its amplitude and phase of the predetermined filter impulse response is adjusted by means of the phase and absolute value of the determined maximum peak sample. Finally, the aggregated baseband carrier signal and the adjusted predetermined filter impulse response are combined by synchronizing their maximum peaks and their opposite phase values for adjusting the aggregated baseband carrier signal to said pre-set threshold value.
