Patent ID: 8223871

Claim:
A method, comprising: adapting a rake receiver having a plurality of rake fingers based on a plurality of received signals, wherein the plurality of received signals correspond to a single signal i) transmitted by a single antenna transceiver, and ii) received by a multiple antenna transceiver that includes the rake receiver, wherein each of a plurality of groups of rake fingers corresponds to a single-input, multiple output (SIMO) channel estimate; selecting one coefficient from each of the plurality of SIMO channel estimates according to one of i ) ⁢ ⁢ max l ⁢ ∑ i = 0 R - 1 ⁢ ⁢  h l i  ⁢ ⁢ or ⁢ ⁢ ii ⁢ ) ⁢ ∑ i = 1 R ⁢ max l ⁢  h l i  , wherein h l i are SIMO channel coefficients corresponding to an estimate of an l th SIMO channel between a respective one of the antennas of the multiple antenna transceiver and the single antenna transceiver, wherein l varies between 0 and L−1, wherein L is a number of SIMO channels, and wherein R is a number of coefficients in each of the SIMO channel estimates; generating a transmit steering vector based on the selected coefficients; and applying the transmit steering vector to a signal to be transmitted by the multiple antenna transceiver to the single antenna transceiver.
