Systems and methods for MIMO wireless transmission are provided. At the transmitter, a plurality of encoded packets are modulated, and the symbols are divided between several transmit antennas. The transmitter spreads some of the symbols of each packet using a respective subset of an available Walsh code space. A given transmit antenna then transmits part of each packet spread by the respective subset. In some implementations, this achieves the benefits of the PARC system, and at the same time achieves part of the benefits of the STTD system. Advantageously, only a single reverse link control channel is required if adaptive coding and modulation is to be performed.
