Abstract
The present invention relates to a method for transmitting data between a transmitter provided with at least two transmitting antennas (ta1, ta2 . . . taNt) and a receiver. The method according to the invention further includes a symbol spreading step in the course of which components Zij (for i=I to S and j=I to Nt) of a predetermined number of successive symbols ZI . . . ZS are to be spread over time before being transmitted over said transmitting antennas (ta1, ta2 . . . taNt). The data transmitted at any given moment will thus not be representative of a single symbol Zi (for i=1 to S), as is the case in known MIMO systems, but will represent a mixture between Nt components of S successive symbols, which introduces data diversity with respect to time as perceived at the receiver end.
