1. A satellite communication system comprising:

  • a satellite comprising;

    a first transponder configured to form a first communication channel having a first polarization of a first polarization format; and

    a second transponder configured to form a second communication channel having a second polarization of the first polarization format;

    wherein the first transponder is configured to receive via the first communication channel at a first frequency slot a first combination of signals including a first linear combination of a first signal and a second signal, the first signal being transmitted by a first terminal via a third communication channel having a third polarization of a second polarization format, the second signal being transmitted by a second terminal via a fourth communication channel having a fourth polarization of the second polarization format,wherein the second transponder is configured to receive via the second communication channel at the first frequency slot a second combination of signals including a second linear combination of the first signal and the second signal, andwherein the first polarization format is different from the second polarization format.
