Methods and systems are provided for increasing bandwidth efficiency in satellite communications. In some embodiments, a satellite communications method is provided that comprises receiving, at a satellite and from a plurality of user ground terminals, a plurality of source signals, wherein each of the source signals are modulated according to at least one source modulation method, and further receiving, at a satellite and from a plurality of user ground terminals, a plurality of information signals corresponding to the plurality of source signals. The method further includes combining, at the satellite, the plurality of source signals into a combined source signal with an overlapping bandwidth, wherein each of the source signals are further modulated according to at least one predetermined modulation method before they are combined, and transmitting, by a downlink transmission from the satellite to a gateway ground station, the combined source signal.
A method for use in a satellite communication system, comprising:
A system for satellite communications, the system comprising one or more digital signal processors at one or more satellites, the one or more digital signal processors being configured to perform operations comprising:
A non-transitory computer-readable medium storing instructions executable by one or more hardware processors of one or more satellites to carry out operations comprising:
