Title (EN) LOG-LIKELIHOOD RATIO ALGORITHM FOR USE IN REDUCING CO-CHANNEL INTERFERENCE IN WIRELESS COMMUNICATION SYSTEMS
(FR) LOGARITHME DU RAPPORT DE VRAISEMBLANCE DESTINÉ À RÉDUIRE LE BROUILLAGE DANS LE MÊME CANAL DANS LES SYSTÈMES DE COMMUNICATION SANS FIL
Abstract:
(EN) In one embodiment, an apparatus includes a receiver configured to receive a transmission from a wireless communication device, the transmission associated with resource units, a detector configured to generate log-likelihood ratio data from the received transmission, and a controller configured to calculate noise and interference for each of the resource units and modify the generated log-likelihood ratio data based on the calculated noise and interference.
(FR) Dans un mode de réalisation, un appareil comprend un récepteur conçu pour recevoir d'un dispositif de communication sans fil une transmission associée à des unités de ressources, un détecteur conçu pour générer des données de rapport de vraisemblance à partir de la transmission reçue, et un contrôleur conçu pour calculer le bruit et le brouillage pour chacune des unités de ressources et modifier les données de rapport de vraisemblance générées sur la base du bruit et du brouillage calculés.
