Abstract: | This paper investigates subset antenna transmission (SAT) for multiple-input multiple-output (MIMO) systems in the presence
of strong dominant co-channel interferer. The capacity gain from SAT is investigated in the context of optimal antenna subset
selection and power allocation. The SAT does not require channel state information of the co-channel interference, and achieves
capacity gains by distributing the transmit power equally over a selected subset of the transmit antennas. The capacity gain
of the SAT method is analyzed in terms of transmit power and eigenvalues of channel matrix, and its performance in V-BLAST
MIMO systems with various signal constellations is evaluated by computer simulation. |
