Proposed onboard signal processing system for communications satellites performs real-time conversion of multiple uplink (received) signals in single-channel-per-carrier, frequency-division-multiple-access (SCPC/FDMA) format to downlink (transmitted) signals in time-division-multiplexed (TDM) format. Conversion approach enhances use of allocated spectrum and reduces required effective isotropic radiated power at both transponder (satellite) and Earth stations. Equipment needed to implement scheme less complex and less expensive than time-division-multiple-access (TDMA) formats. More economical future satellite communication systems made possible through use of many small-capacity multiservice Earth terminals.
