ABSTRACT:
A method of transmitting data on multiple carriers is disclosed, the method consisting, on a transmitter side, of binary to signal coding of the data to be transmitted so as to form modulation signals, of modulating a plurality of sub-carriers with the modulation signals as to form symbols, referred to as OFDM symbols, and then of transmitting, over a channel between the transmitter and a receiver, the OFDM symbols at a rate which is related to a sampling frequency referred to as the transmitter sampling frequency, and, on the receiver side, of determining, from a clock signal at a frequency related to a sampling frequency referred to as the receiver sampling frequency, an analysis window for the signal received from the transmitter so as to form a block of samples, and of estimating the transmitted modulation signals by demodulating the sub-carriers for the block of samples under consideration.
