Abstract:
Disclosed is a method for estimating a CFO, the method comprising: measuring a size ratio of a signal pair received in two consecutive OFDM symbols of a predetermined subcarrier; determining the received signal pair as a signal pair to be used for estimating a residual CFO when the size ratio is within a first threshold range; and estimating the residual CFO, using only the received signal pair which has been determined to be used for estimating the residual CFO.
