Methods and apparatus for coupling a satellite to an earth terminal
First Claim
1. An apparatus for coupling a satellite to an earth terminal, comprising:
- a plurality of inputs of the satellite configured to receive a plurality of digital uplink signals;
an autoscaling digital multiplexer of the satellite configured to digitally multiplex said plurality of digital uplink signals to produce a digital composite signal;
a digital modulator of the satellite configured to digitally modulate said digital composite signal to produce a digitally modulated composite signal;
an input of the earth terminal configured to receive said digitally modulated composite signal;
a digital demodulator of the earth terminal configured to digitally demodulate said digitally modulated composite signal received by said input of the earth terminal to produce a second digital composite signal;
an autoscaling digital demultiplexer of the earth terminal configured to digitally separate said second digital composite signal into a second plurality of digital uplink signals; and
a modulator of the earth terminal configured to modulate said second plurality of digital uplink signals to produce a plurality of modulated analog signals.

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