Abstract:
1. A method for reducing cosite interference, comprising: receiving a first transmitted signal via a plurality of receiving antennas, the first transmitted signal includes a first training sequence; a plurality of received signals, each received signal including the first transmitted signal, and a cosite interference signal, the cosite interference signal includes a cosite training sequence; directing the plurality of received signals to a processing device; directing a cosite sample signal to the processing device, the cosite sample signal includes the cosite training sequence; for each receiving antenna that receives the received signal: phase aligning the equalized signals to produce a plurality of aligned signals; phase aligning the cosite equalized signals to produce a plurality of cosite aligned signals; directing the plurality of aligned signals and the plurality of cosite aligned signals to a combiner; summing the plurality of aligned signals based on the first training sequence and the plurality of cosite aligned signals based on the cosite training sequence to produce a first processed signal; and directing the first processed signal to one of a plurality of receivers based on the first training sequence.
