An Orthogonal Frequency Division Multiplexing (OFDM) receiver that compensates for FFT window drift by extracting pilots (62) from a fast Fourier transformed (56) and equalized (58) OFDM signal, and processing the extracted pilots to derive an FFT window adjustment factor (65) and an associated equalizer tap adjustment value (67). The OFDM receiver simultaneously controls the position of an FFT window and the phase of equalizer taps using the derived FFT adjustment factor and equalizer tap adjustment value.
