Abstract
Data transmission using spatial spreading in a MIMO communication system. For data transmission using spatial spreading, a transmitting entity (1) encodes and modulates each data packet to obtain a corresponding data symbol block, (2) N of a MIMO channel multiplexes the data symbol blocks onto the N S data symbol streams for transmission on the S transmission channels, the the N S data symbol streams with (3) steering matrices (4) N S spreading symbols for full CSI transmission on the N S eigenmodes of the MIMO channel or for partial CSI transmission on the N S spatial channels Process the stream spatially. Receiving entity, (1) N via the R receive antennas to obtain the N R received symbol streams, (2) N S number of the detected full-CSI transmission and to obtain a symbol stream performs receiver spatial processing for the partial-CSI transmission is the N S detected using the (3) the N S of the same steering matrices used by the transmitting entity to obtain the recovered symbol streams And (4) demodulate and decode each reconstructed symbol block to obtain a corresponding decoded data packet.
