Abstract:
A method and apparatus for combining space-frequency block coding (SFBC), spatial multiplexing (SM) and beamforming in a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system. The system includes a transmitter with a plurality of transmit antennas and a receiver with a plurality of receive antennas. The transmitter generates at least one data stream and a plurality of spatial streams. The number of generated spatial streams is based on the number of the transmit antennas and the number of the receive antennas. The transmitter determines a transmission scheme in accordance with at least one of SFBC, SM and beam forming. The transmitter transmits data in the data stream to the receiver based on the selected transmission scheme.
Abstract:
The invention relates to a method and a transmitter for transmitting data using multiple-input multiple-output, MIMO, orthogonal frequency division multiplexing, OFDM, the method comprising: a transmitter generating at least one input data stream; the transmitter generating a plurality of spatial streams; the transmitter determining a transmission coding scheme, and processing the input data stream in accordance with the transmission coding scheme to generate at least two spatial streams, the transmission coding scheme being one of spatial multiplexing, SM, without frequency diversity, FD, wherein one data symbol is sent per one sub-carrier for each spatial stream; and the transmitter transmitting the at least two spatial streams via the generated spatial streams.
