METHODS FOR TRANSMITTING AND RECEIVING AN OQAM-TYPE MULTICARRIER SIGNAL

摘要

The invention relates to a method for receiving a received signal corresponding to a multicarrier signal formed by a temporal succession of symbols consisting of a set of data elements with real values, including at least informative data elements. Said reception method comprises a step of first overall estimation of the transmission channel. According to the invention, due to doubles (23) respectively consisting of at least two informative data elements (23₁, 23₂) being each located in an adjacent region (24₁), and a proportion between said real values of a same double (23) being known by a receiver, said reception method comprises, for at least one of said neighbouring regions, a step of extracting (32) at least two complex values, and a step of locally refining (33) the first estimation, taking into account the complex values. The modulation involved is an OQAM modulation for OFDM.
