Null deepening for an adaptive antenna based communication station
First Claim
1. A method comprising:
- computing an antenna processing strategy to define a transmitted signal or to process a received signal for a remote user, based at least in part on received signal data;
determining signature data of one or more interferers; and
modifying the antenna processing strategy to realize an improved null toward at least one interferer by incorporating the determined signature data of the one or more interferers with the received signal data to reduce one or both of antenna transmit signal strength in, and sensitivity of the antenna to signals from, one or more interferers.

Abstract
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.
