Patent ID: 8687720

Claim:
A method for processing a received signal (r) from a multi-carrier transmitter ( 1 ) with filter banks, by a multi-carrier receiver ( 2 ) with filter banks, the method comprising the steps of: receiving (E1) by a multi-carrier receiver a multi-carrier signal transmitted by a multi-carrier transmitter ( 1 ) comprising filter banks, said multi-carrier signal being generated to a filter bank synthesis of several sub-strings of OQAM symbols, the received multi-carrier signal comprising a synchronisation preamble known by the multi-carrier receiver ( 2 ), said preamble of the signal being a sequence of BPSK symbols, the sequence of BPSK symbols having been pre-coded in OQAM by the multi-carrier transmitter ( 1 ) at the transmission of the multi-carrier signal; analysing (E2) by filter banks of the multi-carrier received signal (r) so as to extract the preamble in a frequency domain; processing (E3) the extracted preamble for obtaining an estimation of data of a propagation channel ( 30 ) located between the multi-carrier transmitter and the multi-carrier receiver.
