Crest factor reduction for a multicarrier-signal with spectrally shaped single-carrier cancelation pulses |
摘要 |
A method for crest factor reduction of a multi-carrier signal is disclosed. The multi-carrier signal comprises a plurality of single-carrier signals, each single-carrier signal having signal-specific spectral properties. The method comprises identifying a peak in the multi-carrier signal and a time of occurrence of the peak and generating a plurality of cancellation pulses depending on the time of occurrence of the peak. A particular cancellation pulse of the plurality of cancellation pulses is associated with a particular single-carrier signal and cancellation pulse-specific spectral properties of the particular cancellation pulse substantially match the signal-specific spectral properties of the associated particular single-carrier signal. The method further comprises combining the plurality of cancellation pulses to form a combined cancellation pulse and applying the combined cancellation pulse to the multi-carrier signal to reduce the peak. A corresponding circuit and corresponding computer program products useable during manufacture and operation are also disclosed. |
