A method and apparatus is described for modifying a smart antenna
processing strategy determined from a set of signals received at an array
of antenna elements of a wireless station, such as a set of weights for
processing received antenna signals or forming a set of antenna signals
for transmission. The method and apparatus uses the signatures of one or
more interferers to produce a modified processing strategy that improves
the nulling to the one or more interferers in that, when the modified
strategy is applied on the downlink, the transmit signal strength in the
direction of the one or more interferers is decreased, and, when the
modified strategy is applied on the uplink, the sensitivity to signals
from the direction of the one or more interferers is decreased.
