An apparatus to establish bi-directional digital communication over a power line network includes a signal launching circuit (305T) to impose a digital communication signal onto a power signal carried by a power line network. The signal launching circuit is configured to position a pulse of the digital communication signal at any phase location of each half cycle of the power signal. A receiver (306) leads the digital communication power signal at a second point in the power line network. A signal processor (604) is connected to the receiver to recover the digital communication signal from the digital communication power signal.

La présente invention concerne un appareil d'établissement de communication numérique bidirectionnelle via un réseau à ligne électrique comprenant un circuit d'émission de signaux (305T) produisant un signal de communication numérique dans un signal de puissance porté par un réseau à ligne électrique. Le circuit d'émission de signaux est configuré de façon à placer une impulsion du signal de communication numérique à n'importe quelle point de phase de chaque moitié de cycle du signal de puissance. Un récepteur (306) entraîne le signal de communication numérique à un second point du réseau à ligne électrique. Un processeur de signaux (604) est relié au récepteur pour récupérer le signal de communication numérique provenant du signal de puissance.
