Patent attributes
In one implementation, a wireless communications terminal includes a multi-element antenna. In addition, the terminal includes preliminary signal combiners to combine received signals output by corresponding pairs of antenna elements. For each preliminary signal combiner, the signal output by a first of the pair of elements provides a model of interference present in the received signal output by the second of the pair of elements. The preliminary signal combiner is configured to combine the signal output by the first element with the signal output by the second element to produce an initial interference-mitigated signal. The terminal also includes phase shifters to apply complex weights to interference-mitigated signals to produce complex-weighted versions of the interference-mitigated signals and effectively steer a main beam of the antenna to facilitate reception of a desired signal and another signal combiner to combine the complex-weighted versions of the interference-mitigated signals to produce an interference-mitigated output signal.
