摘要:
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. While generating the synchronization correlation data, the radio apparatus identifies a first set of one or more peaks in the synchronization correlation data, and determines first synchronization information from the first set of one or more peaks. After generating more of the synchronization correlation data, the radio apparatus identifies a second set of one or more peaks in the synchronization correlation data, and determines second synchronization information from the second set of one or more peaks.
