Patent ID: 7492843

Claim:
A device to synchronize a wireless receiver, comprising: at least two antennas operable to receive wireless signals including at least a first antenna operable to receive a first wireless signal and a second antenna operable to receive a second wireless signal; at least two correlation components including a first and second correlation components, the first correlation component operable to calculate a first metric representing the correlation between a first training field of the first wireless signal and a first known content of the first training field, the first metric having a first maximum, the second correlation component operable to calculate a second metric representing the correlation between a second training field of the second wireless signal and a second known content of the second training field, the second metric having a second maximum; a synchronization component operable to select one of the first and second metrics as a preferred metric based on the greater of the first and the second maximums; and at least two synchronization state machines each operable to generate a synchronization signal related to the preferred metric, the synchronization state machines coupled to the synchronization component and operable such that the first synchronization state machine generates a first synchronization signal and the second synchronization state machine generates a second synchronization signal.
