Abstract:
A multipath processor for processing a plurality of groups of spread-spectrum signals, each group having a plurality of spread-spectrum signals, said multipath processor comprising:first means for despreading a first plurality of spread-spectrum signals within a first group, to generate a first plurality of despread signals, the first spreading means includes a first plurality of correlators for despreading, respectively, the first plurality of spread-spectrum signals, thereby generating the first plurality of despread signals, each correlator of the first plurality of correlators despreads with a chipping-sequence signal having a time delay different from each time delay of each chipping-sequence signal used with other correlators of the first plurality of correlators; first means for combining the first plurality of despread signals as a first combined-despread signal; second means for despreading a second plurality of spread-spectrum signals within a second group, to generate a second plurality of despread signals, the second despreading means includes a second plurality of correlators for despreading, respectively, the second plurality of spread-spectrum signals, thereby generating the second plurality of despread signals, each correlator of the second plurality of correlators despreads with a chipping sequence signal having a time delay different from each time delay of each chipping-sequence signal used with other correlators of the second plurality of correlators, and having the time delay different from each time delay of each chipping-sequence signal used with other correlators of the first plurality of correlators; second means for combining the second plurality of despread signals, as a second combined-despread signal; means for combining the first combined-despread signal and the second combined-despread signal, as an output-despread signal; a first plurality and a second plurality of weighting devices, the first plurality of weighting devices for weighting the first plurality of despread signals, and the second plurality of weighting devices for weighting the second plurality of despread signals; and a first and second weighting device, the first weighting device for weighting the first combined-despread signal, and the second weighting device for weighting the second combined despread signal.
