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.

摘要： Coding and decoding schemes useful in the context of MIMO (Multiple Input Multiple Output) or MISO (Multiple Input Single Output) communications especially used in conjunction of OFDM-like transmission schemes. A space frequency block code (SFBC) is based on the simultaneous use of two variants of Alamouti codes in the frequency domain, each kind of Alamouti code being applied to well-chosen pair of frequencies. The proposed SFBC keeps the constant envelope property for each antenna while leading to performance equal or very close to the pure Alamouti STBC performance.
