Title (EN) ANALOG ACTIVE CANCELLATION OF A WIRELESS COUPLED TRANSMIT SIGNAL
(FR) ANNULATION ANALOGIQUE ACTIVE D'UN SIGNAL DE TRANSMISSION COUPLE SANS FIL
Abstract: front page image
(EN)An active cancellation device receives a model of a first signal from a local wireless transmitter. The first signal causes a coupled signal that interferes in a second signal received by a local wireless receiver from a remote wireless transmitter. The active cancellation device generates a cancellation signal based on the model of the first signal, and provides the cancellation signal to the local wireless receiver. At the local wireless receiver, the cancellation signal combines with the coupled signal and the second signal. The cancellation signal reduces the interference in the second signal caused by the coupled signal.
(FR)La présente invention concerne un dispositif d'annulation active qui reçoit un modèle de premier signal en provenance d'un émetteur sans fil local. Le premier signal entraîne la formation d'un signal couplé qui interfère avec un second signal reçu par un récepteur sans fil local en provenance d'un émetteur sans fil éloigné. Le dispositif d'annulation active de l'invention génère un signal d'annulation sur la base du modèle de premier signal et transmet le signal d'annulation au récepteur sans fil local. Dans le récepteur sans fil local, le signal d'annulation est combiné avec le signal couplé et avec le second signal. Le signal d'annulation réduit l'interférence provoquée par le signal couplé dans le second signal.
