Abstract
A device includes circuitry configured to receive orthogonal frequency-division multiplexing (OFDM) symbols of a training sequence via two or more receive antennas, and circuitry configured to correlate training samples of the OFDM symbols received via the two or more receive antennas to generate a correlation result, estimate a frequency offset using an angle of the correlation result, and correct samples of training symbols in at least one multiple-in-multiple-out (MIMO)-OFDM frame using the frequency offset.
