Abstract
A rake receiver having a plurality of rake fingers is adapted based on a plurality of received signals. The plurality of received signals correspond to a single signal transmitted by a single antenna transceiver and received by a multiple antenna transceiver that includes the rake receiver. Each of a plurality of groups of rake fingers corresponds to a single-input, multiple output (SIMO) channel estimate. One coefficient from each of the plurality of SIMO channel estimates is selected, and a transmit steering vector is calculated based on the selected coefficients. The transmit steering vector is applied to a signal to be transmitted by the multiple antenna transceiver to the single antenna transceiver.
