ABSTRACT:
A method for transmitting data between at least three nodes of an orthogonal frequency-division multiplexing network, including assigning to each node at least one transmit frequency and one receive frequency, the assigned frequencies being different from one node to the other; forming data symbols to be transmitted all having the same duration whatever the transmission node; and adding, to each transmitted symbol, a cyclic prefix and a cyclic suffix reproducing a predetermined number of samples, respectively of the end and of the beginning of the symbol.
