Patent attributes
A system for communication via satellite between a gateway and a plurality of terminals comprises: a controller device to calculate a time-frequency plan of burst signals from a terminal and to transmit, based on the time-frequency plan, to the terminal information including configuration information on transmit burst signals; a multi-carrier demodulator structure arranged to receive a resulting signal comprising receive signals and arranged to receive information for the receive signals. The multi-carrier demodulator structure has multi-carrier demodulator devices, each with a channelizer to serialize the receive signals, yielding a serialized stream of sample segments corresponding to the receive signals, a processing block to receive that stream of sample segments and to perform demodulation of the sample segments based on the sample segment content, on a state indicative of the receive signal to which the sample segment belongs and on said receive information, pre-FEC word aggregation, demapping and decoding.
