ABSTRACT:
A system for identifying transmission parameters of an OFDM signal transmitted according to a transmitter clock includes a first correlator to receive and correlate samples of the signal sampled according to a receiver clock and provide a first metric indicative of whether the signal has a first transmission mode, a plurality of additional correlators, operable in parallel with the first correlator, to receive and correlate the samples of the signal sampled according to the receiver clock and provide a plurality of additional metrics indicative of whether the signal has a second transmission mode and whether the receiver clock is aligned with or displaced by at least one sample over one OFDM symbol relative to the transmitter clock, and a processor. The processor receives the metrics, and determines whether the signal has the first or second transmission mode and whether the receiver clock is aligned or displaced by the at least one sample relative to the transmitter clock.
