METHODS FOR TRANSMITTING AND RECEIVING AN OFDM-TYPE MULTICARRIER SIGNAL, AND CORRESPONDING PILOTS

摘要

The invention relates to a method for receiving a received signal corresponding to a multicarrier signal transmitted by at least one transmitter via a transmission channel, said multicarrier signal being 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 said symbols. According to the invention, due to groups (221) of at least two pilots (P1, P2) being respectively located in an adjacent region (22) in the time/frequency space, such a reception method comprises a step of extracting at least two complex values corresponding to the pilots of the group of the adjacent region, once they have passed through the transmission channel, and a step of estimating said transmission channel in the adjacent region on the basis of said complex values.The modulation used is of the type OFDM OQAM.
