Title
(EN) METHOD AND DEVICE FOR PHASE MODULATION OF A CARRIER WAVE AND APPLICATION TO THE DETECTION OF MULTI-LEVEL PHASE-ENCODED DIGITAL SIGNALS

Abstract
(EN)
The method for phase modulation of a carrier wave involves creating a set of signals sh(t) constituted by a wave of carrier frequency fc of which the phase φ(t) = hφ0(t) is modulated in time t such that sh(t) = cos(2πfct+ hφ0(t)), where h is an integer and where φ0(t) = 2arctan((t - t0)/w0). The modulation corresponds to a single-phase pulse centred at time t0 with positive characteristic duration w0 and incrementing the phase of the signal sh(t) by the quantity h2π, in such a way as to directly generate a single-sideband frequency spectrum. The carrier wave can be electromagnetic or acoustic. The method can be applied, in particular, to the transport of a piece of binary information by single sideband phase encoding, to the generation of orthogonal single-sideband signals, to the detection of multi-level phase-encoded digital signals having a single sideband, to the in-phase and out-of-phase transmission of phase-encoded binary signals having a single sideband, and to a mixed amplitude/phase single-sideband modulation.
(FR)
Le procédé de modulation de phase d'une onde porteuse est tel que l'on crée un ensemble de signaux sh (t) constitués d'une onde de fréquence porteuse fc dont la phase φ(t) =h φ0(t) est modulée dans le temps t de telle sorte que sh (t) = cos(2π fct+ h φ0 (t) ), où h est un nombre entier et où φ0(t) = 2 arctan((t - t0)/ w0). La modulation correspond à une impulsion de phase unique centrée au temps t0 de durée caractéristique w0 positive et incrémentant la phase du signal sh (t) de la quantité h 2 π, de telle sorte que l'on génère directement un spectre de fréquence à bande latérale unique. L'onde porteuse peut être de type électromagnétique ou de type acoustique. Le procédé s'applique notamment au transport d'une information binaire par codage de phase à bande latérale unique, à la génération de signaux orthogonaux à bande latérale unique, à la détection de signaux numériques multi-niveaux codés en phase à bande latérale unique, à l'émission en phase et hors phase de signaux binaires codés en phase à bande latérale unique, ainsi qu'à une modulation mixte amplitude-phase à bande latérale unique.
