Abstract:
1. A method in an orthogonal frequency division multiplexing (OFDM) receiver, comprising at least one receive antenna, to perform synchronization, the OFDM receiver configured to communicate with a transmitter comprising at least one transmit antenna, the method comprising: at each of the at least one receive antenna, sampling a received signal to produce a respective set of time domain samples; determining at least one coarse synchronization position; at each of the at least one receive antenna: a) for each of a plurality of candidate fine synchronization positions about one of said at least one coarse synchronization position: b) determining a fine synchronization position from the correlation values; using the fine synchronization position from each of the at least one receive antenna in an overall fine synchronization position.
