A common phase value of pilot subcarriers of a received data symbol (n) is estimated and used for correcting the phase of all subcarriers of the data symbol, wherein, with a time-variant frequency of the local oscillator (VCO), the estimated noisy phase values (Ψn) are used directly for the phase and frequency correction, whereas with a time-invariant frequency after the VCO, a corrected phase value ({circumflex over (φ)}n) is determined from the estimated phase values of the current data symbol (Ψn) and earlier data symbols (Ψm) in a linear FIR filter arrangement (17-20) and is used for the phase correction.
