ABSTRACT:
Methods and apparatus are provided for coupling an earth terminal to a satellite The apparatus comprises multiple inputs of the earth terminal configured to receive multiple digital communication signals, a autoscaling digital multiplexer of the earth terminal configured to digitally multiplex the multiple digital communication signals to produce a digital composite signal, and a digital modulator of the earth terminal configured to digitally modulate the digital composite signal to produce a digitally modulated composite signal. In addition, the apparatus comprises an input of the satellite configured to receive the digitally modulated composite signal, and a digital demodulator of the satellite configured to digitally demodulate the digitally modulated composite signal received by the input of the satellite to produce a second digital composite signal. Furthermore, the apparatus comprises a autoscaling digital demultiplexer of the satellite configured to digitally separate the second digital composite signal into a second plurality of digital communication signals, and a modulator of the satellite configured to modulate the second plurality of digital communications signal to produce multiple modulated analog signals.
