Title (EN) MODULATION AND DEMODUALTION METHODS FOR POLARIZED SIGNAL TRANSMISSION PRESENTING AN IMPROVED BIT RATE
(FR) PROCÉDÉS DE MODULATION ET DE DÉMODULATION POUR UNE TRANSMISSION DE SIGNAL POLARISÉ PRÉSENTANT UN DÉBIT BINAIRE AMÉLIORÉ
Abstract:
(EN) The invention concerns a modulation method for modulating a stream (S) of binary data into a polarized signal (PS), the method comprising : providing a segment from the stream (S) of binary data, the segment comprising at least 4 bits; extracting two bits from the segment; decoding the two bits to select a modulation scheme among four binary phase shift keying modulation scheme presenting distinct constellation diagrams; and modulating the remaining bits of the segment into the polarized signal using the selected modulation scheme. The invention also relates to the converse demodulation method.
(FR) L'invention concerne un procédé de modulation servant à moduler un flux (S) de données binaires en un signal polarisé (PS), le procédé consistant à : fournir un segment à partir du flux (S) de données binaires, le segment comprenant au moins 4 bits ; extraire deux bits du segment ; décoder les deux bits pour sélectionner un schéma de modulation parmi quatre schémas de modulation par déplacement de phase binaire présentant des diagrammes de constellation distincts ; et moduler les bits restants du segment dans le signal polarisé à l'aide du schéma de modulation sélectionné. L'invention concerne également le procédé inverse de démodulation.
