摘要：A receiving system 100 is disclosed which includes at least one antenna 101providing a plurality of antenna beams providing signal diversity between communicatedsignals. A first processing branch 103 is included for processing a first plurality of signalsappearing within a first plurality of the antenna beams. The first processing branch 103includes a plurality of signal paths, some of which include delays 105, each receiving a oneof the first plurality of signals from a corresponding one of the first plurality of antennabeams. Delays 105 apply a predetermined amount of delay proportionate to the

corresponding one of the beams. First processing branch 103 further includes a combiner106 for combining the first plurality of signals after output from the plurality of signalpaths. A second processing branch 104 is provided for processing a second plurality ofsignals appearing within a second plurality of the antenna beams. Second processingbranch 104 includes a plurality of signal paths, some of which include delays 105, eachreceiving one of the second plurality of signals from a corresponding one of the secondplurality of antenna beams. Delays 105 applying a pre- selected amount of delay to thecorresponding one of the beams. Second processing branch 104 further includes acombiner 106 for combining the second plurality of signals after output from the

plurality of signal paths. Finally, a radio 102 is provided having a first port coupled to anoutput of first processing branch 103 and a second port coupled to a second processingbranch 104.
