Packet interleaving method

A packet interleaving method comprising:

• selecting successive input sets of consecutive input packets (X1 . . . XNin) received from a forward correction module, each input packet (Xj) being a vector of constellation points of a predetermined constellation diagram, wherein
• the packet interleaving method comprises, for each input set:
• generating an output set of output packets (O1 . . . ONout), each output packet (Om) being a vector of constellation points, by distributing the constellation points of each input packet (Xj) of the input set between the output packets (O1 . . . ONout) of the output set,
• sending the output packets (O1 . . . ONout) of the output set to a modulator configured for generating, from the output packets (O1 . . . ONout), a waveform (W), destined to be provided to an antenna,
• the input set comprising Nin input packets (X1 . . . XNin) and each of the Nin input packets (X1 . . . XNin) comprising a same number Lin of constellation points, the number Nout of output packets in the output set is related to Lin by the relation Lin=A×Nout, where A is a fixed whole number.
