    摘要: Values representative of modulation signal components are extracted from a modulated signal. The modulated signal contains a modulation signal. A local clock signal is developed which correlates in time to the modulated signal and has a plurality of non-overlapping phase sectors per cycle. The modulated signal is accumulated into an accumulated value, separately for at least one phase sector of one cycle of the local clock signal. Each accumulated value is representative of a modulation signal component. The modulated signal accumulated is of an amount representative of the mathematical integral of the modulated signal during each phase sector of the local clock over which the modulated signal is accumulated.

    摘要: The invention relates to a method for detecting at least two amplitude-modulated transmission signals, each of which has a different frequency shift, in the same frequency channel, said transmission signals being contained in a received signal. A modified received signal is ascertained (S10) from the received signal by processing the received signal in a nonlinear manner. Subsequently, the spectrum of the modified received signal is determined by means of a Fourier transformation (S20), and at least two transmission signals contained in the received signal are detected (S30-S100) if at least two first spectral lines associated with respective carrier signals can be significantly differentiated from spectral components associated with noise signals and useful signals in the ascertained spectrum.

    摘要: Un traitement effectué par un démodulateur numérique permet de recevoir une transmission (401) en rafale sans utilisation de préambule (Fig 3b) destinée à l'acquisition de la synchronisation. On suppose que la technique de modulation est une modulation par déplacement de phase bivalente (MDPB) (250) ou une modulation par déplacement de phase quadrivalente (MSPQ) (250). Les fonctions de synchronisation (506), de filtrage (504, 505) et de détection nécessaire pour le démodulateur sont exécutées séquentiellement par traitement numérique répété d'échantillons stockés (501) de bandes de base complexes de la rafale (401) de transmission reçue.
