Christian Glattli, Yves Louët, Jacques Palicot, Christophe Moy, Preden RoulleauAbstractIn the present paper, we propose a new frequency-shift keying continuous phase modulation (FSK–CPM) scheme having, by essence, the interesting feature of single-sideband (SSB) spectrum providing a very compact frequency occupation. First, the original principle, inspired from quantum physics (levitons), is presented. Besides, we address the problem of low-complexity coherent detection of this new waveform, based on orthonormal wave functions used to perform matched filtering for efficient demodulation. Consequently, this shows that the proposed modulation can operate using existing digital communication technology, since only well-known operations are performed (e.g., filtering, integration). This SSB property can be exploited to allow large bit rates transmissions at low carrier frequency without caring about image frequency degradation effects typical of ordinary double-sideband signals.RésuméDans cet article, nous présentons un schéma de modulation à phase continue basé sur une nouvelle forme d'onde, ayant la propriété de générer directement un signal avec un spectre à bande latérale unique (la bande inférieure ou supérieure à la fréquence porteuse). Tout d'abord, le principe de base de cette nouvelle forme d'onde, issue de la physique quantique...
