US Patent 10044543 Reducing crest factors

The present disclosure describes methods, systems, and computer program products for a reducing crest factors. An input signal is received. The input signal includes a clipping signal that reduces a peak amplitude of a source signal based on a predetermined clipping level. The input signal is transposed to a plurality of transposed signals using a plurality of multipliers. A feedback signal is generated based on the plurality of transposed signals using a first plurality of delay taps. A windowing signal is generated based on the feedback signal. The windowing signal is used to reduce a crest factor of the source signal.
