The present invention concerns a method for correcting a frequency shift on symbols received by a receiver, each symbol being composed of N samples and of a cyclic prefix of a predetermined number &Dgr; samples, the &Dgr; samples being a copy of &Dgr; samples of the N samples. The receiver: - calculates for each symbol, a correlation between at most the &Dgr; samples of the cyclic prefix and the at most &Dgr; samples among the last samples, - averages the correlations over a number of symbols and determines one smooth frequency shift estimation for each averaged correlation, - calculates an exponential from the smooth frequency shift estimation, - delays the received symbols by a delay, - multiplies the exponential by the delayed received symbols. |
