Patent ID: 6876672

Claim:
Method of transmitting data on multiple carriers from a transmitter to a receiver, comprising: on the transmitter side, binary to signal coding of the data to be transmitted so as to form modulation signals, modulating a plurality of sub-carriers with said modulation signals so as to form signals, referred to as OFDM symbols, transmitting, over a channel between said transmitter and said receiver, said OFDM symbols at a rate which is related to a sampling frequency referred to as the transmitter sampling frequency, and on the receiver side, 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 estimating said transmitted modulation signals by demodulating said sub-carriers for said block of samples under consideration, wherein said estimation comprising correcting the changes in the position of the analysis window with respect to said transmitted signal without slaving said receiver sampling frequency.
