Method and system for transmitting satellite signals and receiver thereof
First Claim
1. A method for transmitting a satellite signal comprising a data stream that includes a sequence of data packets, said method comprising:
- subdividing said data packets of said data stream, through means for splitting, into a first and at least one second data pseudo-streams;
modulating said first and said at least one second data pseudo-streams through a first and at least one second modulators, respectively;
transmitting said modulated data pseudo-streams through respective transmission channels,wherein, in order to generate said data pseudo-streams, said means for splitting will;
select each data packet of said data stream;
interrogate said modulators in a sequential manner in order to identify that modulator which, among said modulators, is available to accept said data packet, and send the latter to it;
send a null data packet to the remaining modulators.

Abstract
A transmission system, a receiver and a method for satellite signal transmission, wherein the satellite signals includes respective data streams consisting of a sequence of data packets. The method includes: subdividing the data packets of the data stream, through a splitter, into a first and at least one second data pseudo-streams; modulating the first and at least one second data pseudo-streams through a first and at least one second modulators, respectively; transmitting the modulated data pseudo-streams through respective transmission channels (Ch#1 . . . Ch#N), wherein, in order to generate the data pseudo-streams, the splitter will: select each data packet of the data stream; interrogate the modulators in a sequential manner in order to identify that modulator which, among the modulators, is available to accept the data packet, and send the latter to it; send a null data packet to the remaining modulators.

11. A transmitter comprising:
-
a splitter configured to receive a data stream; and wherein the splitter is configured to subdivide data packets of said data stream into a first and at least one second data pseudo-streams; a first and at least one second modulator configured to modulate, respectively, said first and said at least one second data pseudo-streams; a transmitter configured to transmit said modulated data pseudo-streams through respective transmission channels, wherein, in order to generate said data pseudo-streams, said splitter is configured to; select each data packet of said data stream; interrogate said modulators in a sequential manner in order to identify that modulator which, among said modulators, is available to accept said data packet, and send the latter to it; send a null data packet to the remaining modulators.

12. A method for receiving a satellite signal comprising a data stream that includes a sequence of data packets, said method comprising the steps of:
-
receiving modulated data pseudo-streams through respective transmission channels; demodulating said first and said at least one second data pseudo-streams through a first and at least one second demodulators, respectively; merging said first and said at least one second data pseudo-streams, through means for merging, in order to reconstruct a data stream comprising packet sequences, wherein, in order to reconstruct said packet stream, said means for merging will; re-align said packet pseudo-streams on the basis of the value of a field of said data packet; select, for each data packet of said re-aligned pseudo-streams, the one that contains a non-null packet; insert said non-null packet into the reconstructed data stream. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A receiver for receiving a satellite signal that includes a data stream including a sequence of data packets, the receiver comprising:
-
a receiver configured to receive modulated data pseudo-streams through respective transmission channels, wherein the modulated data pseudo-streams include a first and at least one second data pseudo-stream; a first and at least one second demodulator configured to demodulate, respectively, said first and said at least one second data pseudo-streams; a merger configured to merge said first and said at least one second data pseudo-streams in order to reconstruct the data stream that includes the sequence of data packets, wherein, in order to reconstruct said packet stream, said merger is configured to; re-align said packet pseudo-streams on a basis of a value of a field of said data packet; select, for each data packet of said re-aligned pseudo-streams, the one that contains a non-null packet; and insert said non-null packet into the reconstructed data stream. - View Dependent Claims (20)
