Abstract
A method for increasing the amount of information bits comprised in a symbol transferred by a source to at least one receiver. The symbol is representative of a modulated base sequence obtained by encoding a sequence of base bits selected by the source and by modulating the encoded selected sequence. The modulated base sequence has fixed points. The source encodes the selected sequence of base bits and a sequence of supplementary bits, obtains a modulated base sequence by modulating the encoded selected sequence of base bits, obtains a modulated altering sequence by modulating the sequence of supplementary bits, alters the modulated base sequence by modifying at least a part of the values of its fixed points using the modulated altering sequence in order to obtain a modulated altered sequence, and transfers the modulated altered sequence under the form of an altered symbol.
