METHOD FOR TRANSMITTING DATA IN A MIMO TELECOMMUNICATION SYSTEM OFFERING A HIGH DIVERSITY AS PERCEIVED FROM A RECEIVER END

摘要

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=1 to S and j=1 to Nt) of a predetermined number of successive symbols Z1...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
