Title (EN) CONCATENATED DECODING METHODS FOR RANGE EXTENSION
(FR) PROCÉDÉS DE DÉCODAGE CONCATÉNÉ POUR EXTENSION DE PLAGE
Abstract:
(EN) Systems and methods are disclosed for decoding wireless signals. For example, a wireless device may receive a wireless signal, de-interleave the received wireless signal to produce a first encoded signal and a second encoded signal, generate a first set of a priori log likelihood ratios (LLRs) by decoding and de-interleaving the first encoded signal, and recover a set of information bits from the received wireless signal based at least in part on the second encoded signal and the first set of a priori LLRs.
(FR) L'invention concerne des systèmes et des procédés de décodage de signaux sans fil. Par exemple, un dispositif sans fil peut recevoir un signal sans fil, désentrelacer le signal sans fil reçu pour produire un premier signal codé et un second signal codé, générer un premier ensemble de rapports de vraisemblance logarithmique a priori (LLR)) via le décodage et le désentrelacement du premier signal codé, et extraire un ensemble de bits d'informations à partir du signal sans fil reçu sur la base, au moins en partie, du second signal codé et du premier ensemble de LLR a priori.
