A radio apparatus is configured to correlate signal data with stored synchronization data to generate synchronization correlation data. The signal data represents a received radio-frequency signal that encodes a data frame having a synchronization preamble comprising a plurality of instances of a predetermined synchronization sequence. The stored synchronization data represents the predetermined synchronization sequence. The synchronization correlation data is generated by correlating signal data representing the synchronization preamble with the stored synchronization data.
