摘要： In one implementation, an antenna array has a plurality of antenna element, each of which is configured to apply a phase shift to a signal. A beam steering controller is configured to steer a main beam of the antenna by controlling the phase shifts applied by the antenna elements. In addition, the beam steering controller also is configured to detect a failure of an antenna element and, in response to detecting the failure, disable the failed antenna element and modify the phase shifts applied by remaining ones of the antenna elements.

摘要： In one implementation, a wireless communication terminal includes a primary antenna array and a first controller configured to steer a main beam of the primary antenna array in a desired direction. The wireless communication terminal also includes an auxiliary antenna array and a second controller configured to control complex weights to be applied by at least some antenna elements of the auxiliary antenna array to corresponding variants of a second signal received by the at least some auxiliary antenna elements. Furthermore, the wireless communication terminal includes at least one signal combiner configured to combine variants of the second signal received from auxiliary antenna elements into an interfering signal that models interference from a co-located wireless communication terminal and subtract the interfering signal from variants of the first signal received from antenna elements of the principal antenna array to produce an interference mitigated signal.

摘要： 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.
