<p>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 ” samples, the ” samples being a copy of ” samples of the N samples. The receiver:
- calculates for each symbol, a correlation between at most the ” samples of the cyclic prefix and the at most ” 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.</p> |
