Patent

CA 2434768

A data compression device comprises at least two pulse generating devices (212, 222); a delay element (211, 221), modulating means (214, 224) and pulse compression element (215, 225) associated with each pulse generating device; and control means (240); whereby each modulated, compressed, pulse is multiplexed onto an optical fibre. The compression may be applied in the time domain or the spatial domain.

L'invention concerne un dispositif de compression de données comprenant au moins deux dispositifs générateurs d'impulsions (212, 222), un élément de retard (211, 221), une unité de modulation (214, 224) et un élément de compression d'impulsions (215, 225) associé à chaque dispositif générateur d'impulsions, ainsi qu'une unité de commande (240), chaque impulsion comprimée modulée étant multiplexée sur une fibre optique. La compression peut être réalisée dans le domaine temporel ou le domaine spatial.
