WebMar 12, 2024 · The baseband equivalent magnitude and the group delay (normalized by the symbol rate) of the OMUX filter are depicted in Figure 3B. We can see that the magnitude response (solid blue) is within the lower (dashed blue) and upper (dashed dotted blue) spectral mask limits, defined by minimum and maximum 3 dB-bandwidths. WebApr 13, 2024 · Note that SNR is typically defined for a single tone signal. For a modulated signal, the PAPR of the signal needs to be considered. Since the PAPR of a single tone signal is 3 dB, this number needs to be subtracted from the SNR value for a waveform with an arbitrary PAPR value.
