The method involves receiving a multi-carrier signal (E1) generated according to synthesis by filter bank of sub-strings of offset quadrature amplitude modulation (OQAM) symbols, where the received signal (r) comprises a known synchronization preamble i.e. sequence of binary phase shift keying (BPSK) symbols pre-coded in OQAM on transmission. The received signal is analyzed (E2) by the filter bank so as to extract the preamble in frequency domain. The resulting preamble is treated (E3) to obtain estimation data of a propagation channel located between a transmitter and a receiver. An independent claim is also included for a multi-carrier digital communications system. |
