DATA TRANSMISSION WITH SPATIAL SPREADING IN A MIMO COMMUNICATION SYSTEM

摘要

For data transmission with spatial spreading, a transmitting entity (1) encodes and modulates each data packet to obtain a corresponding data symbol block, (2) multiplexes data symbol blocks onto Ns data symbol streams for transmission on Ns transmission channels of a MIMO channel, (3) spatially spreads the Ns data symbol streams with steering matrices, and (4) spatially processes Ns spread symbol streams for full-CSI transmission on Ns eigenmodes or partial-CSI transmission on Ns spatial channels of the MIMO channel. A receiving entity (1) obtains N
