1. A multiple antenna wireless system including a transmitter and a receiver comprising:

  • a reconfigurable large antenna array having a plurality of antennas;

    a plurality of RF chains in the transmitter coupled to the reconfigurable large antenna array;

    a pilot assisted channel estimation means for tracking of a fading channel; and

    an adaptive transmit beamforming means at the transmitter for beamforming the reconfigurable large antenna array,where the receiver measures performance of the fading channel, generates relative channel phase information, and feeds back the relative channel phase information to the transmitter, the system further comprises a plurality of RF phase shifters coupled to the large antenna array, the RF phase shifters being adjusted to perform co-phase transmission (CPT) using the relative channel phase information fed back from the receiver.
