Claim 6:
7. A combining sub-system comprising:
a first filter bank in a first remote antenna unit, wherein the first filter bank is configured to divide a first broadband uplink signal received by the first remote antenna unit of a distributed antenna system into a first plurality of narrowband uplink signals;
a second filter bank in a second remote antenna unit, wherein the first remote antenna unit is configured to divide a second broadband uplink signal received by the second remote antenna unit of the distributed antenna system into a second plurality of narrowband uplink signals;
at least one selector device configured to select a first subset of narrowband uplink signals from the first plurality of narrowband uplink signals and a second subset of narrowband uplink signals from the second plurality of narrowband uplink signals based on the first subset of narrowband uplink signals and the second subset of narrowband uplink signals having a characteristic indicative of useful information;
at least one combiner device configured to combine the selected first subset of narrowband uplink signals and the selected second subset of narrowband uplink signals for routing to a base station, wherein the at least one combiner device is configured to exclude narrowband uplink signals outside the selected first subset of narrowband uplink signals and the selected second of narrowband uplink signals from the combining operation.
