Title (EN) RECEIVER AND A METHOD FOR DETECTING CHANNEL OCCUPANCY OF A RADIO CHANNEL
(FR) RÉCEPTEUR ET PROCÉDÉ DE DÉTECTION D'OCCUPATION DE CANAL D'UN CANAL RADIO
Abstract:
(EN) A receiver for detecting channel occupancy of a radio channel is provided. The receiver includes an oscillation circuit configured to generate an oscillation signal. The oscillation circuit is configured to alternate a frequency of the oscillation signal between at least two different frequency values. Further, the receiver includes a down-conversion circuit configured to generate, based on a received radio frequency signal and the oscillation signal, one of an in-phase component and a quadrature component of a baseband signal. The receiver additionally includes a processing circuit configured to calculate, based on the in-phase component or the quadrature component, a signal power of the radio frequency signal.
(FR) L'invention concerne un récepteur conçu pour détecter l'occupation de canal d'un canal radio. Le récepteur comprend un circuit d'oscillation configuré pour générer un signal d'oscillation. Le circuit d'oscillation est configuré pour faire alterner une fréquence du signal d'oscillation entre au moins deux valeurs de fréquence différentes. En outre, le récepteur comprend un circuit de conversion descendante configuré pour générer, sur la base d'un signal radiofréquence reçu et du signal d'oscillation, l'une d'une composante en phase et d'une composante en quadrature d'un signal de bande de base. Le récepteur comprend en outre un circuit de traitement configuré pour calculer, sur la base de la composante en phase ou de la composante en quadrature, une puissance de signal du signal radiofréquence.
