Abstract
Presented is a satellite communication system that allows aggregation of available transponder bandwidth. A channel signal is divided into subchannels if no full transponder is available to receive the channel signal in its entirety, and the subchannels are distributed among a available bandwidths in a plurality of transponders. At the receiving station, the subchannels are combined to form the original channel signal. The channel signal, whether divided and reconstructed or transmitted without being divided, are received into a switch matrix that receives a user channel selection and identifies the channel signal that corresponds to the selection. The identified channel signal is then demodulated and forwarded to a user interface unit. Only a single demodulator is necessary for a user interface unit.
