Abstract :
A method is presented for calculating the spectral regrowth generated by a digitally modulated carrier passed through a nonlinear microwave circuit. Spectral regrowth is calculated from the probability density function (pdf) of the modulation amplitude and a complex power series nonlinear model based on measured AM-AM and AM-PM data of a nonlinear device. Calculation of spectral regrowth allows efficient evaluation of the impact of modulation format on spectral regrowth.
