Claim 0:
1. A method for reducing crest factors, the method comprising:
receiving a plurality of first samples of a first input signal, the plurality of first samples generated at a first sampling rate;
performing a first peak detection based on the plurality of first samples to generate a plurality of first peak detection output samples;
downsampling the plurality of first peak detection output samples to generate a plurality of first windowing input samples at a second sampling rate;
generating a plurality of first windowing output samples based on the plurality of first windowing input samples;
upsampling the plurality of first windowing output samples to generate a plurality of first peak reduction samples at the first sampling rate; and
generating a first output signal based on the plurality of first samples and the plurality of first peak reduction samples.
