Abstract:
According to various embodiments, a method is disclosed that includes a method is disclosed that includes determining, by a receiver, a frequency offset in a signal comprising a set of orthogonal frequency division multiplexed (OFDM) symbols by determining a first difference in phase angles between a nth OFDM symbol and a nth+1 OFDM symbol on a common OFDM carrier and a first difference in phase angles between the nth+1 OFDM symbol and a nth+2 OFDM symbol on the common OFDM carrier and determining a second difference in phase angles between the first difference in phase angles between the nth OFDM symbol and the nth+1 OFDM system and the first difference in phase angles between the nth+1 OFDM symbol and the nth+2 OFDM symbol to identify the frequency offset, wherein nε{1, . . . , N}; and correcting, by the receiver, the signal using the determined frequency offset.
