Abstract: Communication system includes first unit; and second unit(s) having processing unit(s), downstream signal path(s), and upstream signal path(s). First unit communicates downstream digital transport signal (including digital representation of original downstream RF signal received at first unit) to second unit(s). Second unit uses processing unit and downstream signal path to generate downstream RF signal (for radiation from antenna) from downstream digital transport signal; and communicates upstream digital transport signal (generated from upstream RF signal received at second unit(s) using processing unit(s) and upstream signal path(s)) to first unit. Upstream digital transport signal includes digital representation of received upstream RF signal. Feedback path digitizes downstream RF signal(s) to provide digital representation(s) of downstream RF signal radiated from antenna to processing unit(s). Second unit pre-distorts input signal to downstream signal path for non-linearities in downstream signal path using digital representation of downstream RF signal radiated from antenna as received from feedback path.

Abstract: A host unit (for use within a DAS having a plurality of remote units communicatively coupled to the host unit) includes a plurality of base transceiver stations and a switch. Each base transceiver station is configured to operate on a RF channel. Each base transceiver station is configure to provide a downstream baseband digital signal to the switch and to receive an upstream baseband digital signal from the switch. Each downstream and upstream baseband digital signal is a digital representation of the RF channel at baseband of the respective base transceiver station. The switch is configured to route each downstream baseband digital signal to a respective subset of the remote units as one or more downstream serial data streams and to route each upstream baseband digital signal from one or more upstream serial data streams to a respective subset of the base transceiver stations.

Abstract: A summing unit within telecommunications system includes: port to receive digital data stream from another device; and summer function. Digital data stream includes first and second digital data derived from first and second base station. First and second digital data comprises first and second digital values associated with respective time periods. Summing unit extracts first digital data from digital data stream. Summer function digitally sums first digital data with third digital data derived from third base station to generate summed digital data for conversion to radio frequency signals and transmission at antenna. Third digital data comprises third series of third digital values associated with respective time periods. Summer function digitally sums first digital data with third digital data by digitally summing (i) first digital value associated with respective time period and (ii) third digital value associated with respective time period to produce summed value for respective time period.
