Schmidl Cox Synchronization#

class SchmidlCoxSynchronization(waveform=None)[source]#

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:: List[int]
Returns:: List of time indices indicating the first samples of frames detected in signal.
Raises:: RuntimeError – If the synchronization routine is floating
