Abstract
An uplink demodulator system ( ) for use in a processing satellite ( ) in a satellite based communications system ( ) is provided with a first multiplexer ( ), a second multiplexer ( ), a multichannel preamble processor ( ), and a multichannel phase tracker ( ). The first multiplexer ( ) is operable to receive channelized data from a plurality of channelization modes at a plurality of inputs and operable to route the channelized data to a first output. The multichannel preamble processor ( ) is operable to determine a phase estimate for each channel of the channelized data. The multichannel phase tracker ( ) is operable to receive the phase estimates from the multichannel preamble processor ( ) and operable to track a phase for each channel of said channelized data to phase align each channel of said channelized data to corresponding uplink signals. The second multiplexer ( ) is operable to multiplex and route heavy encoded channelized data and light encoded channelized data to a second output where the multiplex channelized data is phase aligned with the corresponding uplink signals.
