Claim 0:
1. A method comprising:
receiving a first broadband uplink signal with a first remote antenna unit of a distributed antenna system and a second broadband uplink signal with a second remote antenna unit of the distributed antenna system;
dividing, at the first remote antenna unit, the first broadband uplink signal received with the first remote antenna unit into a first plurality of narrowband uplink signals;
dividing, at the second remote antenna unit, the second broadband uplink signal received with the second remote antenna unit into a second plurality of narrowband uplink signals;
selecting 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, wherein the characteristic indicative of useful information includes at least one of a signal power above a threshold signal power or a correlation characteristic; and
combining the selected first subset of narrowband uplink signal and the selected second subsets of narrowband uplink signals for routing to a base station, wherein combining the selected first subset of narrowband uplink signals and the selected second subset of narrowband uplink signals comprises excluding narrowband uplink signals outside the selected first subset of narrowband uplink signals and the selected second subset of narrowband uplink signals from the combining operation.
