The disclosed embodiments relate to a system and method for processing digital communication signals. An exemplary system (100) comprises a first input adapted to receive a first digital communication signal (103a), a second input adapted to receive a second digital communication signal (103b), an upconverter (102) adapted to generate a multichannel digital signal that incorporates data corresponding to the first digital signal (103a) at a first frequency and data corresponding to the second digital signal (103b) at a second frequency, and a digital-to-analog converter (108) adapted to convert the multichannel digital signal to a multichannel analog signal.
