1. A method of transmitting OFDM signals between a plurality of spatially separated transmit antennas and at least one receive antenna, the method comprising:

  • determining relative timing differential values for the plurality of transmit antennas when the transmit antennas transmit OFDM signals to the at least one receive antenna via at least one diverse path, wherein the relative timing differential values result in a timing misalignment; and

    resolving the timing misalignment by allocating the relative timing differential values among the one or more diverse paths; and

    grouping the spatially separated transmit antennas into zones based at least in part on timing characteristics.
