Abstract
SPACE SPREADING DATA TRANSMISSION IN A MIMO COMMUNICATION SYSTEM For spatially spread data transmission, a transmission entity (1) encodes and modulates each data packet to obtain a corresponding data symbol block, (2) multiplexes the blocks. (2) multiplexes the data symbol blocks into N ~ s data symbol streams for transmission into N ~ s MIMO channel transmission channels, (3) spatially spreads the N ~ s data arrays with steering arrays, and (4) spatially processes N- s scattered symbol streams for full Node auto-CSI transmission or partial CSI transmission on N-channel spatial channels of the MIMO channel. A receiving entity (1) obtains N ~ r ~ received symbol streams through N ~ r ~ receiving antennas, (2) performs receiver spatial processing for full CSI transmission or partial CSI transmission to obtain N ~ s ~. detected symbol streams, (3) spatially disperse the detected symbol streams with the same direction arrays used by the transmitter to obtain recovered symbol streams, and (4) demodulate and decode each block. retrieved to obtain a corresponding decoded data packet.
