Patent ID: 8526525

Claim:
A method for communicating a radio signal between a first station and a second station, comprising: estimating at least one characteristic of a radio channel from the first station comprising a first plurality of weightable transceiving elements, to the second station comprising a second plurality of weightable transceiving elements, wherein estimating the at least one characteristic includes estimating the characteristic c ij of the radio channel from element i of the first plurality of weightable transceiving elements to element j of the second plurality of weightable transceiving elements, for at least a portion of the first plurality of weightable transceiving elements and at least a portion of the second plurality of weightable transceiving elements and forming a channel estimate matrix C A from the estimated characteristics c ij that includes the estimate of the at least one characteristic; calculating a receive weighting of at least one weightable transceiving element at the second station, responsive to the estimate; calculating a transmit weighting of at least one weightable transceiving element at the first station; weighting the first plurality of weightable transceiving elements with the transmit weighting to form transmit-weighted transceiving elements at the first station; weighting the second plurality of weightable transceiving elements with the receive weighting to form receive-weighted transceiving elements at the second station; and communicating the radio signal by transmitting from the transmit-weighted transceiving elements at the first station, over the radio channel, to the receive-weighted transceiving elements at the second station.
