Method for transmitting optimally diversified information in a MIMO telecommunication system

摘要

The present invention relates to a method for transmitting data between a transmitter TR and a receiver REC via communication channels CHNL. The method according to the invention further includes a symbol spreading step in the course of which a tunable integer number K of successive symbols Z1 . . . ZK are to be spread over several time chips before being transmitted, said tunable number K being adjusted with respect to physical properties of the communication channels CHNL. The data transmitted at any given moment will thus not be representative of a single symbol Zi, as is the case in known MIMO systems, but will represent a mixture between K successive symbols, which introduces data diversity with respect to time as perceived at the receiver end, and enables a tuning of the communication throughput between the transmitter TR and the receiver REC.
