For comparative purposes a spectrum of a transmitted signal without feedback correction is displayed with one that accounts for correction:
• You can see from the "Power Spectrum" plot that the feedback circuit significantly reduces the spectral regrowth of the transmitted signal
As the simulation is running you can tune:
• On the power level of the QPSK signal
• The 1dB compression point of the main amplifier
• The delay element in the feedback loop (at a certain point the delay value will have a major impact on the effectiveness of the feedback circuit.
