1. A method of adaptively beamforming data for an antenna array, comprising the steps of:

  • (a) receiving in a current frame, an RF signal emanating from a mobile station;

    (b) obtaining a spatial location associated with a previous frame of the signal;

    (c) calculating beamforming weights based on pre-training sequence data of the current frame of the signal and the spatial location;

    (d) applying the beamforming weights to the antenna array data to process the current frame; and

    (e) estimating an updated spatial location associated with the current frame based on training sequence data of the current frame; and

    (f) maintaining the updated spatial location for use with a future frame of the signal.
