Methods and OFDM receivers for decoding an OFDM signal. The method includes estimating a channel impulse response from a pilot-dense symbol of the OFDM signal for each of a plurality of potential FFT window positions; determining a noise floor of each of the channel impulse responses; selecting the potential window position corresponding to the channel impulse response with the lowest noise floor as an optimum FFT window position; and decoding symbols of the OFDM signal using the optimum FFT window position. To be accompanied, when published, by FIG. 5 of the accompanying drawings. |
