1. A signal interface unit for a distributed antenna system, comprising:
a channelized radio carrier interface configured to communicate respective uplink individual baseband data for uplink radio carrier channels for a radio frequency carrier to a channelized radio carrier base station interface;
an antenna side interface configured to receive uplink distributed antenna system baseband data for the uplink radio carrier channels from the distributed antenna system communicatively coupled to the antenna side interface; and
a signal conversion module communicatively coupled between the channelized radio carrier interface and the antenna side interface and configured to convert between the uplink distributed antenna system baseband data for the uplink radio carrier channels and the respective uplink individual baseband data for the uplink radio carrier channels at least in part by performing, for each respective uplink radio carrier channel of the uplink radio carrier channels, an adjustment of the uplink distributed antenna system baseband data for the respective uplink radio carrier channel received from the distributed antenna system to comply with requirements of the channelized radio carrier base station interface.
