Multi-antenna transmission system and method

Abstract

The invention discloses a multi-antenna transmission system and a multi-antenna transmission method. A transmitter of the system comprises a spatial modulation module, a single-carrier modulation module, a cyclic prefix insertion module, a digital/analogue (D/A) conversion module and a first radio frequency link module. The system is characterized in that: the transmitter also comprises a data distribution module and a first antenna selection module. According to the method, an information bit stream to be transmitted is divided into two paths through data distribution, wherein one path comprises information for controlling serial numbers of antennae, and is directly transmitted to an antenna selection module, and the other path comprises data information bits which are modulated, subjected to radio frequency processing and then transmitted to the antenna selection module; and then an antenna is selected to transmit information. Therefore, compared with the conventional method, the method has the advantages that: the number of radio frequency links is decreased; and system cost is decreased.
