ABSTRACT:
A base station for communicating with at least one mobile station in a cellular communications system includes a plurality of receive antennas wherein each receive antenna is oriented to define a respective receive coverage area. The antennas are supported by a support structure so that a first receive antenna defines a first receive coverage area and a second receive antenna defines a second receive coverage area overlapping a portion of the first receive coverage area. First and second wideband receivers are operatively connected to respective first and second antennas. The first wideband receiver receives a first plurality of receive channels from the first receive coverage area, and the second wideband receiver receives a second plurality of receive channels from the second receive coverage area. The first and second pluralities of receive channels include at least one common receive channel. The base station also includes first and second channel splitters operatively connected to the respective first and second wideband receivers for separating the first and second pluralities of receive channels. A diversity combiner is operatively connected to the first and second channel splitters for combining the common receive channel from the first and second channel splitters. Accordingly, an enhanced quality output receive channel is produced.
