EVM degradation of time-domain (pre-FFT) decoded OTA transmissions with respect to the frequency-domain (post-FFT) counterpart (M=30, 16-QAM). The EVM degradation is plotted for both perfect IA transmission (absence of interference) and IA transmission (presence of interference). Notice that a 0-dB degradation means that both pre-FFT and post-FFT decoding methods perform the same in terms of EVM
