Abstract
A receiving system 100 is disclosed which includes at least one antenna 101 providing a plurality of antenna beams providing signal diversity between communicated signals. A first processing branch 103 is included for processing a first plurality of signals appearing within a first plurality of the antenna beams. The first processing branch 103 includes a plurality of signal paths, some of which include delays 105, each receiving a one of the first plurality of signals from a corresponding one of the first plurality of antenna beams. Delays 105 apply a predetermined amount of delay proportionate to the corresponding one of the beams. First processing branch 103 further includes a combiner 106 for combining the first plurality of signals after output from the plurality of signal paths. A second processing branch 104 is provided for processing a second plurality of signals appearing within a second plurality of the antenna beams. Second processing branch 104 includes a plurality of signal paths, some of which include delays 105, each receiving one of the second plurality of signals from a corresponding one of the second plurality of antenna beams. Delays 105 applying a pre-selected amount of delay to the corresponding one of the beams. Second processing branch 104 further includes a combiner 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 an output of first processing branch 103 and a second port coupled to a second processing branch 104.
