Preamble Freq Error (802.16 OFDM)

Preamble Freq Error (Preamble Frequency Error) is the difference between the measured center frequency of the transmitted signal and the VSA’s center frequency. The Preamble Freq Error trace shows the total frequency error during the preamble portion of the OFDM burst. This includes the constant frequency error as displayed in the Syms/Errs trace in addition to any time-varying frequency error.

Preamble Freq Error is sampled at 256 times the subcarrier spacing.
