METHODS FOR THE TRANSMISSION AND RECEPTION OF A MULTICARRIER SIGNAL COMPRISING ISOLATED PILOTS, AND CORRESPONDING DEVICES AND COMPUTER PROGRAM PRODUCTS

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 with real values, including informative data elements, and reference data elements called pilots for at least some of said symbols. Said reception method comprises a step of first estimation of the transmission channel. According to the invention, due to at least one of the pilots being an isolated pilot (23) in transmission, the reception method comprises a step of extracting the isolated pilot, and a step of locally refining said first estimation.
