Abstract
A method for MC-CDMA transmission of data between nodes of a network, including assigning to each node at least one spreading matrix, a set of data of at least one datum to be transmitted by a node being multiplied by the spreading matrix which is associated therewith and the product being then transmitted on a group of carriers in at least one predetermined set of samples forming at least one OFDM symbol; forming symbols to be transmitted all having the same duration, whatever the transmit node; and adding to each transmitted symbol a cyclic prefix and a cyclic suffix representing a predetermined number of samples, respectively of the end and of the beginning of the symbol.
