Downlink multiuser MIMO-OFDM transmission using simple receive antenna selection

摘要

This paper proposes a downlink MU-MIMO-OFDM transmission using simple receive antenna selection. In the proposal, base station transmits to users with selected receive antenna per subcarrier to obtain diversity gain. The proposal also decreases computational complexity by narrowing down the number of antenna combination in accordance with correlation value between receive antennas at each user. From experimental evaluations, it is indicated that the proposal offers high channel capacity with greatly reduced antenna combination.
