A communications system includes a fixed transmitter and a mobile wireless communications device. The fixed transmitter transmits a source signal defined by a character set made up of symbols. At least one of the symbols in the character set is transmitted at a different power level so that the transmitted source signal appears with linearly independent power level time periods. The linearly independent power level time periods are used by the mobile wireless communications device to populate a mixing matrix for signal separation processing.
Selon l'invention, un système de communication comprend un émetteur fixe et un dispositif de communication mobile sans fil. L'émetteur fixe émet un signal source défini par un jeu de caractères constitué de symboles. Au moins un des symboles du jeu de caractères est transmis à un niveau de puissance différent, de sorte que le signal source transmis apparaisse selon des durées de niveau de puissance linéairement indépendantes qui sont utilisée par le dispositif de communication mobile sans fil pour remplir une matrice de mélange pour le traitement de séparation des signaux.
