Abstract  Abstract

In data transmission via spatial spreading, the transmitting entity (1) encodes and modulates each data packet to obtain a corresponding data symbol block, and (2) for transmission on the N S transport channels of the MIMO channel. Multiplex the data symbol blocks into N S data symbol streams, (3) spatially spread the N S data symbol streams by the steering matrix, and (4) a full-CSI transmission or MIMO channel over the N S unique modes It spatially processes the N S spread symbol streams for partial-CSI transmission over the N S spatial channels of. The receiving entity (1) N R receive antennas obtain N R received symbols streams through, (2) the receiver space for the whole or part -CSI -CSI transmission to obtain N S detected symbol streams of Perform processing, (3) spatially despread N S detected symbol streams by the same steering matrices that were used by the transmitting entity to obtain N S recovered symbol streams, and (4) each reconstruct The demodulated symbol stream is demodulated and decoded to obtain a corresponding decoded data packet.
