- class SchmidlCoxSynchronization(waveform=None)[source]¶
Bases:
OFDMSynchronization
Schmidl-Cox Algorithm for OFDM Waveform Time Synchronization and Carrier Frequency Offset Equzalization.
Applying the synchronization routine requires the respective waveform to have a
SchmidlCoxPilotSection
pilot symbol section configured.Refer to Schmidl and Cox[1] for a detailed description.
- Parameters:
waveform (CommunicationWaveform, optional) – The waveform generator this synchronization routine is attached to.
- synchronize(signal)[source]¶
Simulates time-synchronization at the receiver-side.
Sorts base-band signal-sections into frames in time-domain.
- Parameters:
signal (np.ndarray) – Vector of complex base-band samples of with num_streams`x`num_samples entries.
- Return type:
- Returns:
List of time indices indicating the first samples of frames detected in signal.
- Raises:
RuntimeError – If the synchronization routine is floating
