Abstract
A method and system for providing selective interference mitigation (or nulling) in an adaptive array system. A communication device, typically employing an adaptive array, determines an indication of signal reception quality for a first remote user terminal in communication with the communication device. The communication device provides a first mode of operation wherein a first amount of nulling with respect to at least one interfering source is generated by the communication device. In addition, the communication device provides a second mode of operation characterized by generating a second amount of nulling with respect to the at least one interfering source, wherein the second amount of nulling is relatively greater than the first amount of nulling. Based on the relative signal reception quality indication, the communication device selects one of the first and second modes of operation.
