<p>It is proposed a method for receiving and demodulating an orthogonal frequency division multiplexing signal received through a transmission channel (TC) by a receiver (RCV), comprising demultiplexing said signal to generate time symbols (yl(n)) and performing a time-to-frequency conversion of these time symbols to generate frequency bins (Yl(k)) corresponding to received symbols, the received symbols comprising preamble symbols. The method comprises: - Determining an estimated carrier frequency offset on the basis of frequency bins corresponding to used subcarriers of the preamble symbols; - Applying said estimated carrier frequency offset to the time symbols so as to correct the carrier frequency of these received symbols.</p> |
