Method for reducing crest factor of signal, involving generating correction signal as combination of several partial correction signals, each with preset frequency

摘要

Crest factor of signal (X) is reduced by generating correction signal (XK) as combination of several partial correction signal, each with preset frequency. Correction signal is subtracted from processed signal to generate corrected signal with reduced crest factor.Preset frequencies are so chosen that correction signal is periodical, with period length less than length of signal period (XKP) of correction signal is determined and correction signal is defined as periodical continuation of a period. Independent claims are included for appliance for reducing crest factor and signal transmitter respectively.
