A system and method for transmitting multiple independent data streams from subsets of a plurality of transmit antennas. The method includes determining (11 ) by a receiver (50), a transmit antenna partitioning, including relative phase rotations to be applied to each transmit antenna, that results in the highest channel capacity among the possible partitionings. The receiver (50) then provides (12) partitioning information to a transmitter (40), including the number of transmit antenna subsets, which transmit antennas are included in each subset, the capacity of the data stream to be transmitted from each antenna subset, and the relative phase rotations to be applied to the antennas in each subset. The transmitter (40) partitions (35) the plurality of transmit antennas into mutually exclusive subsets in accordance with the partitioning information, applies (38) the relative phase rotation to each transmit antenna, and transmits (39) an independent data stream from each subset of transmit antennas with a rate not greater than the stream capacity. |
