Abstract
A method comprises receiving a transmission including at least two Orthogonal Frequency Division Multiplexing (OFDM) symbols, estimating a sampling frequency offset associated with the OFDM symbols at least in part by employing a term representing a density of pilots in the OFDM symbols, and compensating for the sampling frequency offset using the estimated sampling frequency offset.
