Radio receiver synchronization

A radio apparatus-configured:

• comprising:
• a radio receiver;
• a memory;
• a hardware correlator;
• and
• synchronization and decoding logic,
• wherein the radio receiver is configured to:
• receive a radio-frequency signal as a radio signal, wherein the radio-frequency signal encodes a data frame having a synchronization preamble comprising a plurality of instances of a predetermined synchronization sequence;
• and
• generate signal data representing the received radio-frequency signal from the received radio signal while the radio receiver is receiving the radio signal;
• wherein the memory is configured to store synchronization data representing the predetermined synchronization sequence;
• wherein the hardware correlator is configured to correlate signal data representing the synchronization preamble with the stored synchronization data to generate synchronization correlation data;
• and
• wherein the synchronization and decoding logic is configured,
• while generating the synchronization correlation data, to:
• identify a first set of one or more peaks in the synchronization correlation data;
• determine first synchronization information for the radio apparatus from the first set of one or more peaks;
• and
• synchronize the receiving, by the radio apparatus, of at least a first part of the radio-frequency signal using the first synchronization information;
• and
• wherein the synchronization and decoding logic is configured, after generating more of the synchronization correlation data, to:
• identify a second set of one or more peaks in the synchronization correlation data;
• determine second synchronization information for the radio apparatus from the second set of one or more peaks;
• and
• synchronize the receiving, by the radio apparatus, of at least a second part of the radio-frequency signal using the second synchronization information.
