Abstract
A method is provided for receiving a received signal corresponding to a multicarrier signal transmitted by at least one transmitter via a transmission channel. The multicarrier signal is formed by a temporal succession of symbols consisting of a set of data elements including informative data elements with real values, and pilots for at least some of the symbols. Due to groups of at least two pilots being respectively located in an adjacent region in the time/frequency space, the reception method includes a step of extracting at least two complex values corresponding the pilots of the group of the adjacent region, once they have passed through the transmission channel, and a step of estimating the transmission channel in the adjacent region on the basis of the complex values. The modulation used is the type of OFDM OQAM.
