Abstract :
The regrowth of digital data power spectra due to amplifier nonlinearity is analyzed. The frequency-domain expression for the amplifier output shows how spectral regrowth will depend on the cubic coefficient of the Taylor´s series of the amplifier nonlinearity as well as the combination of input phase modulation and amplitude ripple. A new, canonical “para-spectrum” is introduced that depends only on the signal and figures critically in the sidelobe regrowth calculation
