Patent ID: 8458535

Claim:
A packet interleaving method comprising: a calculator device selecting successive input sets of consecutive input packets (X 1 . . . X Nin ) received from a forward correction module, each input packet (X j ) being a vector of constellation points of a predetermined constellation diagram, the consecutive input packet being FEC data packets from an FEC decoder, wherein the packet interleaving method comprising the calculator device, for each input set: generating an output set of output packets (O 1 . . . O Nout ), each output packet (O m ) being a vector of constellation points, by distributing the constellation points of each input packet (X j ) of the input set between the output packets (O 1 . . . O Nout ) of the output set, sending the output packets (O 1 . . . O Nout ) of the output set to a modulator configured for generating, from the output packets (O 1 . . . O Nout ) a waveform (W), destined to be provided to an antenna, and the input set comprising N in input packets (X 1 . . . X Nin ) and each of the N in input packets (X 1 . . . X Nin ) comprising a same number L in of constellation points, the number N out of output packets in the output set is related to L in by the relation L in =A×N out , where A is a fixed whole number.
