    Abstract: Single-port weighting systems are shown for applying phase and/or amplitude weights to received signals. One system embodiment includes an array of antenna elements, a microwave power combiner, a plurality of microwave structures and a single microwave downconverter that is coupled to the power combiner and has a single output port for access to the received signals. Each of the microwave structures couple first and second signal paths between a respective one of the antenna elements and the power combiner, insert a phase shift in one of the first and second signal paths and insert first and second mixers respectively in the first and second signal paths wherein the mixers each have an input port for application of the weights.

    Abstract: Methods are disclosed for receiving GPS signals in the presence of multiple interference signals. The methods feature the orthogonal projection of sub-optimal weight vectors onto sets of orthonormal basis vectors. They facilitate the use of single-port reception techniques in which power is monitored only at a single GPS array output port regardless of the number of array elements. The methods do not require prior knowledge of interference signal structure and their use of uncoupled orthonormal basis vectors facilitates the simultaneous adjustment of array weights and rapid convergence to an optimal set of weights.
