METHOD AND DEVICE FOR COMBINING SPACE FREQUENCY BLOCK CODING, SPATIAL MULTIPLEXING, AND BEAM FORMATION IN MIMO-OFDM SYSTEM

摘要

PROBLEM TO BE SOLVED: To solve the problem that a channel must be invariable ranging over a subcarrier to be combined.SOLUTION: Provided are a method and a device for combining space frequency block coding (SFBC), spatial multiplexing (SM), and beam formation in a multi-input multi-output (MIMO) orthogonal frequency division multiple (OFDM) system. This system includes a transmitter 110 equipped with a plurality of transmission antennas 126, and a receiver 130 equipped with a plurality of receiving antennas 128. The transmitter generates at least one data stream and a plurality of spatial streams. The number of generated spatial streams depends on the number of transmission antennas 126 and the number of receiving antennas 128. The transmitter 110 determines a transmission system according to at least one of the SFBC, SM, and beam formation. The transmitter 110 transmits the data of data streams to the receiver 130 on the basis of the selected transmission system.
