1. A signal processing apparatus, comprising:
- a first input adapted to receive a first digital communication signal;
a second input adapted to receive a second digital communication signal;
a combiner for generating a multichannel digital signal that incorporates data corresponding to the first digital signal and data corresponding to the second digital signal; and
an upconverter for converting the frequency of said multichannel digital signal to position the data corresponding to the first digital communication signal as a first channel at the first frequency in the multichannel digital signal and to position the data corresponding to the second digital communication signal as a second channel at the second frequency in the multichannel digital signal.
