Abstract
Approaches for crest factor reduction in a multiband transmitter. An input data signal is placed on a first frequency band, and a second frequency band that is inactive is selected. The second frequency band is out-of-band from the first frequency band. A peak-reducing waveform placed on the second frequency band is generated. The peak-reducing waveform is configured to reduce a plurality of peaks in the data signal. The peak-reducing waveform and the data signal are combined to produce a crest-factor-reduced signal. The crest-factor-reduced signal is transmitted from the multiband transmitter.
