Patent

CA 2364409

A system for communication signals between a transmitter and a receiver using digital modulation techniques is provided. In one preferred embodiment of this invention a modulator is a differential binary shift key modulation. The modulator comprises a digitizer (101), a summer (102), a differential encoder (103), and a phase shifter (104).

L'invention concerne un système de communication de signaux entre un émetteur et un récepteur au moyen de techniques de modulation numérique. Dans un mode de réalisation préféré, le modulateur utilise une modulation de type DBPSK (differential binary phase shift keying). Le modulateur comporte un convertisseur analogique/numérique (101), un sommateur (102), un codeur différentiel (103) et un déphaseur (104).
